Polymer Essay Examples

Spandex fibers were first produced by Farbenfabriken Bayer. He was a pioneer in polymer chemistry and in 1952 earned a German patent for his synthesis. The final development of spandex was produced by scientists at Du Pont and the U. S. rubber Company. Du Pont used the brand name Lycra. They soon began manufacturing in […]

Thermoset process scrap costs companies millions of dollars annually. Specific thermoplastics could benefit from the addition of recycled thermoset material. The incorporation of thermoset regrind into thermoplastic material would provide a viable alternative for the thermoset scrap that is currently sent to the landfills. When a thermoset part has been cross-linked, that material either has […]

Throughout the 20th century, plastics have been an essential part of the market industry. Most plastics are a combination of other organic and inorganic compounds; 20% of the content of a plastic is composed of additives. Biodegradable plastics are usually derived from proteins such as those that are present in a potato plant. Polymers are […]

The formation of nylon by a condensation polymerization reaction at the interface of water and hexane, two immiscible solvents. The lower water layer contains the compound hexanedioyl dichloride, Cl C(CH2)4C O O Cl hexanedioyl dichloride The reaction produces nylon and HCl(aq). The polymer forms at the interface between the two solutions and is drawn out […]

Polymer is a Greek word meaning ‘many parts’. Literally, polymers are substances with many repeating units. This paper will briefly discuss polymers and polymerization as used in chemistry. Definition of a Polymer A polymer is defined as a large molecule that is made up of several structural units connected by chemical bonds. They are in […]

Fossil fuels provide both energy and raw materials such as ethylene, for the production of other substances construct word and balanced formulae equations of chemical reactions as they are encountered. There are three important steps involved:  Show all reactants and all products in the word equation. Write the correct formula for each reactant and each […]

The difference between configuration and conformation is that conformation is used in reference to the outline or have of the chain molecule, configuration refers to the arrangement of atom positions along the chain that are not alterable except by the breaking and reforming Of primary bonds. 15. 9 During the winter months, the temperature in […]
