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.
Physical and Chemical Properties Nylon Fabrics. Composition: The nylons are polyamides with recurring amide groups. They contain carbon, oxygen, nitrogen and hydrogen elements. Strength: Nylon has good tenacity and the strength is not lost with age. Nylon has a high strength to weight ratio.
