When nylon 6/6 is exposed to ambient air temperatures and begins to solidify, mould shrinkage occurs and shapes can change. Nylon 6 is derived from one monomer, which is a molecule that can be bonded to other identical molecules to form polymers. To make nylon 6,6 one doesn't need a catalyst, but acids do catalyze the reaction, and wouldn't you know it, one of the monomers is itself an acid.

A video that models and explores the structure, properties and uses of the condensation polymer, polyester. Nylon 1,6 – It is produced from dinitriles with the help of acid catalysis. Ruchi Upadhyay 12,330 views. The other monomer is a 6 carbon chain with an amino group, -NH 2, at each end. It was found that the mechanical properties of the IPC‐modified nylon 6,6 were improved more than those of the semirigid copolyamides. Another issue with processing nylon materials is moisture and water absorption. Polymers that lack pi electrons, such as polyethylene, can stand up better to UV rays. Industrial synthesis is usually done by heating the acids, amines or lactams to remove water, but in the laboratory, diacid chlorides can be reacted with diamines. The term nylon is used to describe a family of organic polymers called the polyamides that contain the amide (-CONH) group. We find the highest Young's modulus for nylon-7.
