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.
