Since HCl is a by-product of this reaction, a diamine solution which is prepared in an equimolar equivalent of aqueous NaOH is used. NaOH reacts with HCL and forms salt and water. This prevents HCl from side reactions. Nylons are some of the most important fibers produced commercially. Tents,parachutes are made from nylon.But nylon can be more than just fibers. It's used for self-lubricating gears and bearings. Nylon-clay composites are used to make under-hood automobile parts. The two most important kinds of nylon are nylon 6,6 and nylon 6. These two nylons have almost identical properties. Both were invented in the late 1930s. Nylon 6,6 was discovered first. It was invented in the United States by Wallace Carothers who was working for DuPont.​10​ Not long after that Nylon 6 was invented in Germany by Paul Schlack who was working for I.G. Farben.​11 All polymerizations fall into two categories: step-growth polymerizations and chain-growth polymerizations. Both step-growth polymerizations and chain-growth polymerizations are used to make nylons. Making nylon from a diacid and a diamine is a step-growth polymerization. So is making nylon from an amino acid. Making nylon from lactams is usually a chain-growth polymerization. Procedure:
