Polyamides and Polyesters

This set of flashcards covers key terms and concepts related to polyamides, polyesters, their properties, and environmental impacts.

Polyamide

A type of synthetic polymer, including common examples like Nylon.

Nylon

Synthetic aliphatic polyamides known for their strength, resilience, and utility in textiles and engineering.

Nylon 6,6

A specific type of Nylon made from hexamethylenediamine and adipic acid, first commercially produced in 1938.

Nylon 6

Another type of Nylon produced from hexamethylenediamine and caprolactam, with commercial production starting post 1945.

Polyester

Synthetic polymers formed by a reaction between diacids and diols, widely used in fibers and packaging.

PET (Polyethylene Terephthalate)

The most important polyester, known for its high melting temperature and mechanical properties, discovered in 1941.

Transesterification

A process used in the production of PET to increase reaction rates and manage stoichiometric control.

Great Pacific Garbage Patch

A large area in the Pacific Ocean accumulating substantial plastic waste, measuring around 1.6 million square kilometers.

Circular Economy

An economic system aimed at minimizing waste and making the most of resources by reusing, recycling, and maintaining products.

Ionic Ring Opening Polymerisation

A method for producing specific types of Nylon through a chain-growth process.
