what is polyamide
A polyamide is a macromolecule with repeating units linked by amide bonds.Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk.Artificially made polyamides can be made through step-growth polymerization or solid-phase synthesis yielding materials such as nylons, aramids, and sodium poly(aspartate) . polyamide is a macromolecule with repeating units linked by amide bonds.
