Q.Nylon is an example of

Condensation polymers form when functional groups on adjacent, at-least-bifunctional monomers react, eliminating a small molecule (water, ammonia) at each step. Nylon-6,6: from adipic acid + hexamethylene diamine, via an intermediate "nylon salt" that loses water to form amide bonds; used in textiles and tyre cord. Nylon-6: from caprolactam, heated at 533 K with a trace of water; used in tyre-cord fabric. Terylene (Dacron): from ethylene glycol + terephthalic acid, heated at 500 K with zinc acetate/antimony trioxide catalyst; a polyester used blended with cotton/wool and as glass-reinforcement in safety helmets. Bakelite: phenol + formaldehyde, first forming the …
