The other monomer is a 6 carbon chain with an amino group, -NH 2, at each end. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Nylon 6: This polymer is sometimes used to make nylon fabrics, but it is less popular for this application than nylon 6,6. Nylon and Teflon are manmade synthetic polymers that are most widely used in the polymer industry. Types of Nylon 6/6 – Commercial Grade These identical structures, we understand as a unit made up of two or more molecules, join together to form a long chain. Polypropylene vs Nylon. Both were invented in the late 1930s. Start studying Chemistry - Chapter 12. After removal of water and acid, the nylon 6 is melt spun at 250°–260°C into fibers. Nylon 6,6 was discovered first.
