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.
What impact has the development of synthetic fibres such as nylon had on the society? Â· Formed by the combination of coal, petroleum, natural gas, agricultural products, water and air. Â· These materials when heated produce a polymer. Nylon is a synthetic polymer which means it is a long line of repeating subunits.
