When a polymer is dispersed or dissolved in a liquid, such as in commercial products like paints and glues, the chemical properties and molecular interactions influence how the solution flows and can even lead to self-assembly of the polymer into complex structures. When a polymer is applied as a coating, the chemical properties will influence

3848-615: A state, the East German authorities eased border restrictions, but this actually led to an acceleration of the Wende reform process culminating in the Two Plus Four Treaty under which Germany regained full sovereignty. This permitted German reunification on 3 October 1990, with the accession of the five re-established states of the former GDR. The fall of the Wall in 1989 became a symbol of

3996-456: A statistical distribution of chain lengths, the molecular weight is expressed in terms of weighted averages. The number-average molecular weight ( M n ) and weight-average molecular weight ( M w ) are most commonly reported. The ratio of these two values ( M w / M n ) is the dispersity ( Đ ), which is commonly used to express the width of the molecular weight distribution. The physical properties of polymer strongly depend on

Following Hitler's suicide during the Battle of Berlin , Germany signed the surrender document on 8 May 1945, ending World War II in Europe and Nazi Germany. Following the end of the war, surviving Nazi officials were tried for war crimes at the Nuremberg trials . In what later became known as

11544-441: The adhesion of the coating and how it interacts with external materials, such as superhydrophobic polymer coatings leading to water resistance. Overall the chemical properties of a polymer are important elements for designing new polymeric material products. Polymers such as PMMA and HEMA:MMA are used as matrices in the gain medium of solid-state dye lasers , also known as solid-state dye-doped polymer lasers. These polymers have

From these high-performance polymers, the customers manufacture plastic parts, for automobile engineering, mobile phones, display windows, LEDs, packaging, baby bottles, eyeglasses, etc. Ems-Griltech produces hot-melt adhesives (for clothing, automobile electronics, packaging, composites) as well as separating and adhesive yarns for

11988-595: The canton of Graubünden. [9] When, on 13 May 1956, a national referendum decided against the further subsidization of «Hovag» for the years 1956 to 1960 in the amount of CHF 28.3 million, it stopped the production of ethyl alcohol. In 1947, "Inventa AG" was founded for research and patent utilization (later, process engineering and plant engineering were combined). In the mid-1950s "Inventa" built more than 300 plants (117 in China) for caprolactam, plastics and synthetic fibers. Before its acquisition by Christoph Blocher , Ems-Chemie

12136-421: The case of water or other molecular fluids. Instead, crystallization and melting refer to the phase transitions between two solid states ( i.e. , semi-crystalline and amorphous). Crystallization occurs above the glass-transition temperature ( T g ) and below the melting temperature ( T m ). All polymers (amorphous or semi-crystalline) go through glass transitions . The glass-transition temperature ( T g )

12284-522: The communist-controlled Socialist Unity Party of Germany , supported by the Stasi , an immense secret service. While East German propaganda was based on the benefits of the GDR's social programmes and the alleged threat of a West German invasion, many of its citizens looked to the West for freedom and prosperity. The Berlin Wall , built in 1961, prevented East German citizens from escaping to West Germany, becoming

12432-529: The company, he began to focus on engineering plastics and changed the name to "Ems Chemie Holding AG" and "Ems Chemie AG" in 1981. In 1983, he was commissioned, by the founding Oswald family, to find a buyer for the shares of Ems Chemie Holding AG. Blocher decided to take over the Oswald family's share package himself and therefore had the majority voting power at the company. In the following years Ems expanded and took over several other companies. In 1988 Ems focused on

12580-624: The company. At the beginning of 2003, the Blocher family decided that the "Ems" should remain a publicly traded shares company and introduced the unit names shares. On 10 December 2003, Christoph Blocher was elected to the Federal Council. Since a Federal Council member is not allowed to have any economic connections, he gave up all his positions at the "Ems" group and sold his majority stake in "Ems Chemie-Holding AG" to his four children on 30 December. On 1 January 2004, his daughter, Magdalena, took over

12728-469: The continuously linked backbone of a polymer used for the preparation of plastics consists mainly of carbon atoms. A simple example is polyethylene ('polythene' in British English), whose repeat unit or monomer is ethylene . Many other structures do exist; for example, elements such as silicon form familiar materials such as silicones, examples being Silly Putty and waterproof plumbing sealant. Oxygen

12876-547: The country's GDP, well below the NATO target of 2%. In 2024, Germany reported $ 97.7 billion to NATO, exceeding the NATO target of 2% at 2.12% of GDP. Polymer A polymer is a substance composed of macromolecules. A macromolecule is a molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass. A polymer ( / ˈ p ɒ l ɪ m ər / )

13024-462: The creation of a new currency in 1924 ushered in the Golden Twenties , an era of artistic innovation and liberal cultural life. The worldwide Great Depression hit Germany in 1929. Chancellor Heinrich Brüning 's government pursued a policy of fiscal austerity and deflation which caused unemployment of nearly 30% by 1932. The Nazi Party led by Adolf Hitler became the largest party in

13172-466: The creation of a more unified European political, economic and security apparatus. The governments of Germany and the United States are close political allies . Cultural ties and economic interests have crafted a bond between the two countries resulting in Atlanticism . After 1990, Germany and Russia worked together to establish a "strategic partnership" in which energy development became one of

13320-536: The criminal and the protection of the public. With the exceptions of petty crimes, tried by a single professional judge, and of serious political crimes, all charges are adjudicated by mixed tribunals where lay judges ( Schöffen ) and professional judges preside together. As of 2016, Germany's murder rate stood at a low of 1.18 murders per 100,000. In 2018, the overall crime rate fell to its lowest since 1992. Same-sex marriage has been legal in Germany since 2017, and LGBT rights are generally protected in

13468-461: The deaths of an estimated 2.7 million Poles , 1.3 million Ukrainians , 1 million Belarusians and 3.5 million Soviet prisoners of war . German military casualties have been estimated at 5.3 million, and around 900,000 German civilians died. Around 12 million ethnic Germans were expelled from across Eastern Europe, and Germany lost roughly one-quarter of its pre-war territory. After Nazi Germany surrendered,

13616-536: The degree of crystallinity may be expressed in terms of a weight fraction or volume fraction of crystalline material. Few synthetic polymers are entirely crystalline. The crystallinity of polymers is characterized by their degree of crystallinity, ranging from zero for a completely non-crystalline polymer to one for a theoretical completely crystalline polymer. Polymers with microcrystalline regions are generally tougher (can be bent more without breaking) and more impact-resistant than totally amorphous polymers. Polymers with

13764-400: The driving force for mixing is usually entropy , not interaction energy. In other words, miscible materials usually form a solution not because their interaction with each other is more favorable than their self-interaction, but because of an increase in entropy and hence free energy associated with increasing the amount of volume available to each component. This increase in entropy scales with

13912-566: The early 1950s. West Germany joined NATO in 1955 and was a founding member of the European Economic Community . On 1 January 1957, the Saarland joined West Germany. East Germany was an Eastern Bloc state under political and military control by the Soviet Union via occupation forces and the Warsaw Pact . Although East Germany claimed to be a democracy, political power was exercised solely by leading members ( Politbüro ) of

14060-681: The ecclesiastical territories were secularised and annexed. In 1806 the Imperium was dissolved; France, Russia, Prussia, and the Habsburgs (Austria) competed for hegemony in the German states during the Napoleonic Wars . Following the fall of Napoleon , the Congress of Vienna founded the German Confederation, a loose league of 39 sovereign states . The appointment of the emperor of Austria as

14208-614: The entire track system would have to be extended in three tracks to Ems factory. There is no proposed funding for this project. Germany – in Europe  (light green & dark grey) – in the European Union  (light green) Germany , officially the Federal Republic of Germany , is a country in Central Europe . It lies between the Baltic and North Sea to

14356-537: The factories was halted. Between Chur and Domat/Ems runs the narrow-gauge railway line Chur-Domat/Ems of the Rhaetian Railway , which has three tracks since December 1959. Through this, standard gauge freight trains can reach the Ems-Chemie. The RhB stop, Ems factory, serves the factory site directly. There are ideas to introduce normal passenger services to Ems factory in the future. For this purpose, however,

14504-417: The field of organic electronics . Nowadays, synthetic polymers are used in almost all walks of life. Modern society would look very different without them. The spreading of polymer use is connected to their unique properties: low density, low cost, good thermal/electrical insulation properties, high resistance to corrosion, low-energy demanding polymer manufacture and facile processing into final products. For

14652-527: The free energy of mixing for polymer solutions and thereby making solvation less favorable, and thereby making the availability of concentrated solutions of polymers far rarer than those of small molecules. Furthermore, the phase behavior of polymer solutions and mixtures is more complex than that of small molecule mixtures. Whereas most small molecule solutions exhibit only an upper critical solution temperature phase transition (UCST), at which phase separation occurs with cooling, polymer mixtures commonly exhibit

14800-401: The glass transition is not. The glass transition shares features of second-order phase transitions (such as discontinuity in the heat capacity, as shown in the figure), but it is generally not considered a thermodynamic transition between equilibrium states. In general, polymeric mixtures are far less miscible than mixtures of small molecule materials. This effect results from the fact that

14948-597: The government was completed in 1999, and modernisation of the East German economy was scheduled to last until 2019. Since reunification, Germany has taken a more active role in the European Union , signing the Maastricht Treaty in 1992 and the Lisbon Treaty in 2007, and co-founding the eurozone . Germany sent a peacekeeping force to secure stability in the Balkans and sent German troops to Afghanistan as part of

15096-436: The group management as vice-president and Delegate of the board of directors. In the same year "Ems Grivory" was divided into the independent areas "Ems GrivoryEuropa", "Ems Grivory America" and "Ems Grivory Asia". In 2005, Blocher's son Markus's, «Ems Dottikon», was split up as an independent company. The three sisters surrendered their shares to their brother and in return received shares in "Emesta Holding AG". This meant that

15244-508: The highest fully automated high-bay warehouse in Switzerland was put into operation and EMS is selected by General Motors and Bosch as supplier of the year. Foxconn described EMS as the strategic supplier of the year. Ems Chemie lets their apprentices learn in branches abroad. Ems Chemie has two factories in Russia that have 30 employees each. Due to the Russo-Ukrainian war , the production in

In the same year, the special polymers of «Ems Grivory» received the drinking water permit, which allowed new applications in the sanitary sector to be realized. In the following years, "Ems" launched a series of new products and opened new production sites worldwide. In 2010 "Ems Eftec" sold the Aftermarket segment and focused on direct delivery. In 2011, EMS celebrated its 75-year company anniversary; on this occasion Karl Lüönd's released his company biography "Success as an order. «Ems-Chemie»: The History of an Impossible Company". At Domat / EMS,

15688-451: The latter case, increasing the polymer chain length 10-fold would increase the viscosity over 1000 times. Increasing chain length furthermore tends to decrease chain mobility, increase strength and toughness, and increase the glass-transition temperature (T g ). This is a result of the increase in chain interactions such as van der Waals attractions and entanglements that come with increased chain length. These interactions tend to fix

15836-436: The length (or equivalently, the molecular weight) of the polymer chain. One important example of the physical consequences of the molecular weight is the scaling of the viscosity (resistance to flow) in the melt. The influence of the weight-average molecular weight ( M w {\displaystyle M_{w}} ) on the melt viscosity ( η {\displaystyle \eta } ) depends on whether

15984-417: The load is removed. Dynamic mechanical analysis or DMA measures this complex modulus by oscillating the load and measuring the resulting strain as a function of time. Transport properties such as diffusivity describe how rapidly molecules move through the polymer matrix. These are very important in many applications of polymers for films and membranes. The movement of individual macromolecules occurs by

16132-436: The market. Many commercially important polymers are synthesized by chemical modification of naturally occurring polymers. Prominent examples include the reaction of nitric acid and cellulose to form nitrocellulose and the formation of vulcanized rubber by heating natural rubber in the presence of sulfur . Ways in which polymers can be modified include oxidation , cross-linking , and end-capping . The structure of

16280-413: The material will endure before failure. This is very important in applications that rely upon a polymer's physical strength or durability. For example, a rubber band with a higher tensile strength will hold a greater weight before snapping. In general, tensile strength increases with polymer chain length and crosslinking of polymer chains. Young's modulus quantifies the elasticity of the polymer. It

16428-469: The most important factors. As a result of the cooperation, Germany imported most of its natural gas and crude oil from Russia. Germany's development policy functions as a distinct sector within its foreign policy framework. It is formulated by the Federal Ministry for Economic Cooperation and Development and carried out by the implementing organisations. The German government sees development policy as

16576-641: The nation. Germany has a network of 227 diplomatic missions abroad and maintains relations with more than 190 countries. Germany is a member of NATO , the OECD , the G7 , the G20 , the World Bank and the IMF . It has played an influential role in the European Union since its inception and has maintained a strong alliance with France and all neighbouring countries since 1990. Germany promotes

Germany is also bordered by the North Sea and, at the north-northeast, by the Baltic Sea. German territory covers 357,596 km (138,069 sq mi). Elevation ranges from the mountains of the Alps (highest point: the Zugspitze at 2,963 metres or 9,721 feet) in

17020-444: The number of particles (or moles) being mixed. Since polymeric molecules are much larger and hence generally have much higher specific volumes than small molecules, the number of molecules involved in a polymeric mixture is far smaller than the number in a small molecule mixture of equal volume. The energetics of mixing, on the other hand, is comparable on a per volume basis for polymeric and small molecule mixtures. This tends to increase

17168-713: The partially negatively charged oxygen atoms in C=O groups on another. These strong hydrogen bonds, for example, result in the high tensile strength and melting point of polymers containing urethane or urea linkages. Polyesters have dipole-dipole bonding between the oxygen atoms in C=O groups and the hydrogen atoms in H-C groups. Dipole bonding is not as strong as hydrogen bonding, so a polyester's melting point and strength are lower than Kevlar 's ( Twaron ), but polyesters have greater flexibility. Polymers with non-polar units such as polyethylene interact only through weak Van der Waals forces . As

17316-587: The party system has been dominated by the Christian Democratic Union and the Social Democratic Party of Germany . So far every chancellor has been a member of one of these parties. However, the smaller liberal Free Democratic Party and the Alliance 90/The Greens have also been junior partners in coalition governments . Since 2007, the democratic socialist party The Left has been a staple in

17464-455: The people' (from diot or diota 'people'), originally used to distinguish the language of the common people from Latin and its Romance descendants . This in turn descends from Proto-Germanic * þiudiskaz 'of the people' (see also the Latinised form Theodiscus ), derived from * þeudō , descended from Proto-Indo-European * tewtéh₂- 'people', from which

17612-472: The permanent president reflected the Congress's rejection of Prussia 's rising influence. Disagreement within restoration politics partly led to the rise of liberal movements, followed by new measures of repression by Austrian statesman Klemens von Metternich . The Zollverein , a tariff union, furthered economic unity. In light of revolutionary movements in Europe , intellectuals and commoners started

17760-422: The physical arrangement of monomer residues along the backbone of the chain. These are the elements of polymer structure that require the breaking of a covalent bond in order to change. Various polymer structures can be produced depending on the monomers and reaction conditions: A polymer may consist of linear macromolecules containing each only one unbranched chain. In the case of unbranched polyethylene, this chain

17908-399: The polymer and create gaps between polymer chains for greater mobility and fewer interchain interactions. A good example of the action of plasticizers is related to polyvinylchlorides or PVCs. A uPVC, or unplasticized polyvinylchloride, is used for things such as pipes. A pipe has no plasticizers in it, because it needs to remain strong and heat-resistant. Plasticized PVC is used in clothing for

18056-426: The polymer at the scale of a single chain. The microstructure determines the possibility for the polymer to form phases with different arrangements, for example through crystallization , the glass transition or microphase separation . These features play a major role in determining the physical and chemical properties of a polymer. The identity of the repeat units (monomer residues, also known as "mers") comprising

18204-540: The polymer can lend the polymer to ionic bonding or hydrogen bonding between its own chains. These stronger forces typically result in higher tensile strength and higher crystalline melting points. The intermolecular forces in polymers can be affected by dipoles in the monomer units. Polymers containing amide or carbonyl groups can form hydrogen bonds between adjacent chains; the partially positively charged hydrogen atoms in N-H groups of one chain are strongly attracted to

18352-403: The polymer is above or below the onset of entanglements . Below the entanglement molecular weight , η ∼ M w 1 {\displaystyle \eta \sim {M_{w}}^{1}} , whereas above the entanglement molecular weight, η ∼ M w 3.4 {\displaystyle \eta \sim {M_{w}}^{3.4}} . In

18500-583: The polymerization of PET polyester . The monomers are terephthalic acid (HOOC—C 6 H 4 —COOH) and ethylene glycol (HO—CH 2 —CH 2 —OH) but the repeating unit is —OC—C 6 H 4 —COO—CH 2 —CH 2 —O—, which corresponds to the combination of the two monomers with the loss of two water molecules. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue. Synthetic methods are generally divided into two categories, step-growth polymerization and chain polymerization . The essential difference between

18648-458: The production of caprolactam from which polyamide plastics and, from the subsidiary company, Fibron S.A., polyamide fibers (brand names Grilon) were made. Shortly afterwards, the first foreign sales company was founded, GRILON & Plastics Machinery Ltd. based in Dover ( UK ). In 1954 the "Hovag" was one of the largest employers with 1015 employees and consumed about half of the electrical energy of

18796-437: The same side), atactic (random placement of substituents), and syndiotactic (alternating placement of substituents). Polymer morphology generally describes the arrangement and microscale ordering of polymer chains in space. The macroscopic physical properties of a polymer are related to the interactions between the polymer chains. When applied to polymers, the term crystalline has a somewhat ambiguous usage. In some cases,

18944-512: The size of individual polymer coils in solution. A variety of techniques may be employed for the synthesis of a polymeric material with a range of architectures, for example living polymerization . A common means of expressing the length of a chain is the degree of polymerization , which quantifies the number of monomers incorporated into the chain. As with other molecules, a polymer's size may also be expressed in terms of molecular weight . Since synthetic polymerization techniques typically yield

Average monthly hours of sunshine ranged from 45 in November 2019 to 300 in June 2019. The territory of Germany can be divided into five terrestrial ecoregions : Atlantic mixed forests , Baltic mixed forests , Central European mixed forests , Western European broadleaf forests , and Alps conifer and mixed forests . As of 2016 , 51% of Germany's land area

19388-556: The standardization of the language; the 1555 Peace of Augsburg tolerated the "Evangelical" faith ( Lutheranism ), but also decreed that the faith of the prince was to be the faith of his subjects ( cuius regio, eius religio ). From the Cologne War through the Thirty Years' Wars (1618–1648), religious conflict devastated German lands and significantly reduced the population. The Peace of Westphalia ended religious warfare among

19536-448: The states is known as a coil–globule transition . Inclusion of plasticizers tends to lower T g and increase polymer flexibility. Addition of the plasticizer will also modify dependence of the glass-transition temperature T g on the cooling rate. The mobility of the chain can further change if the molecules of plasticizer give rise to hydrogen bonding formation. Plasticizers are generally small molecules that are chemically similar to

19684-722: The subsequent decisive Prussian victory in the Austro-Prussian War of 1866 enabled him to create the North German Confederation which excluded Austria . After the defeat of France in the Franco-Prussian War , the German princes proclaimed the founding of the German Empire in 1871. Prussia was the dominant constituent state of the new empire; the King of Prussia ruled as its Kaiser, and Berlin became its capital. In

19832-412: The supply of 2000 tons of feed yeast per year, of which only a total of 2639 tons were delivered due to supply shortages. From 1944 to 1947, the company invested in patents and administrations AG ("Patvag AG"), a sister company of "Hovag", focused on hydropower plants, in order to secure their energy supplies. In 1948, Hovag began producing ammonia, in 1949 urea synthesis, and in the 1950s Hovag began with

19980-686: The term crystalline finds identical usage to that used in conventional crystallography . For example, the structure of a crystalline protein or polynucleotide, such as a sample prepared for x-ray crystallography , may be defined in terms of a conventional unit cell composed of one or more polymer molecules with cell dimensions of hundreds of angstroms or more. A synthetic polymer may be loosely described as crystalline if it contains regions of three-dimensional ordering on atomic (rather than macromolecular) length scales, usually arising from intramolecular folding or stacking of adjacent chains. Synthetic polymers may consist of both crystalline and amorphous regions;

20424-401: The three sisters held the majority of shares of Ems-Chemie Holding. In the following year, the "Tegra" biomass power plant (wood-chip power plant) was put into operation, reducing CO 2 emissions at the Domat / Ems plant by 80%. In 2007, Miriam Blocher reduced her stake in "Ems-Chemie Holding", the majority was now owned by Magdalena Martullo-Blocher and Rahel Blocher. "Ems Togo" took over all

20572-555: The two is that in chain polymerization, monomers are added to the chain one at a time only, such as in polystyrene , whereas in step-growth polymerization chains of monomers may combine with one another directly, such as in polyester . Step-growth polymerization can be divided into polycondensation , in which low-molar-mass by-product is formed in every reaction step, and polyaddition . Newer methods, such as plasma polymerization do not fit neatly into either category. Synthetic polymerization reactions may be carried out with or without

20720-406: The war and a period of Allied occupation , Germany was organized into two separate polities with limited sovereignty: the Federal Republic of Germany, or West Germany , and the German Democratic Republic, or East Germany . Berlin continued its de jure Four Power status . The Federal Republic of Germany was a founding member of the European Economic Community and the European Union , while

20868-621: The western Rhineland had been incorporated into Roman provinces . Around 260, Germanic peoples broke into Roman-controlled lands. After the invasion of the Huns in 375, and with the decline of Rome from 395, Germanic tribes moved farther southwest: the Franks established the Frankish Kingdom and pushed east to subjugate Saxony and Bavaria . Areas of what is today eastern Germany were inhabited by Western Slavic tribes. Charlemagne founded

21016-597: The word Teutons also originates. Pre-human ancestors, the Danuvius guggenmosi , who were present in Germany over 11 million years ago, are theorized to be among the earliest ones to walk on two legs. Ancient humans were present in Germany at least 600,000 years ago. The first non-modern human fossil (the Neanderthal ) was discovered in the Neander Valley . Similarly dated evidence of modern humans has been found in

21164-531: Was a joint venture between «Eftec» and the Czech company D-Plast to open up the Central and Eastern European market. In 2000, the group was made up of four main self-employed companies "Ems Grivory" (technical thermoplastics), "Ems Griltec" (technical fibers and adhesives), "Ems Primid" (thermosets), "Ems Services" (central services workshop Domat / Ems). The following year Blochers eldest daughter Magdalena Martullo joined

21312-605: Was coined in 1833 by Jöns Jacob Berzelius , though with a definition distinct from the modern IUPAC definition. The modern concept of polymers as covalently bonded macromolecular structures was proposed in 1920 by Hermann Staudinger , who spent the next decade finding experimental evidence for this hypothesis. Polymers are of two types: naturally occurring and synthetic or man made . Natural polymeric materials such as hemp , shellac , amber , wool , silk , and natural rubber have been used for centuries. A variety of other natural polymers exist, such as cellulose , which

21460-514: Was developing a kind of napalm weapon in the 1950s that was used in Indonesia and Yemen. In 1960, "Hovag" was renamed "Emser Werke AG". The founding in 1962 of Chemie Holding Ems AG was listed for the first time on the Vorbörse Zurich on 17 December 1962. In the 1960s, "Emser Werke AG" expanded its product portfolio on an ongoing basis and established independent subsidiaries. In 1963, EMS Patvag
