Nylon was the first commercially successful synthetic thermoplastic polymer. Commercially, nylon polymer is made by reacting monomers which are either lactams, acid/amines or stoichiometric mixtures of diamines (-NH2) and diacids (-COOH). Mixtures of these can be polymerized together to make copolymers.
The chemical name for nylon is polyamide, and the chemical name for polyester is polyethylene naphthalate. Both were first produced in the United States by the DuPont Company, nylon in 1939 and polyester in 1953. Production for both starts from a chemical liquid base that is spun and dried into fibers.
