Vedclass · Answer

(B) Step-growth polymerization involves the reaction of bifunctional or multifunctional monomers to form polymers with the elimination of small molecules like $H_2O$ or $CH_3OH$. Polyesters,such as $Terylene$ (Dacron),are formed by the condensation polymerization of ethylene glycol and terephthalic acid,which is a classic example of step-growth polymerization. Polyethylene,polypropylene,and polystyrene are addition polymers formed by chain-growth polymerization.
