(D) Nylon-6, 6
Condensation polymers are formed through a condensation reaction, where molecules join together, losing small molecules as byproducts.
For e.g., Nylon - 6,6 is formed by condensation polymerization of adipic acid and hexamethylenediamine.
Whereas Polystyrene, Teflon and Rubber all are formed by chain-growth polymerization of monomers styrene, tetrafluoroethylene and isoprene respectively.
Here, an unsaturated monomer molecule adds to the active site of a growing polymeric chain one at a time.
