Vedclass · Answer

(D) Chain-growth polymers are formed by the addition of monomers containing double or triple bonds (e.g.,alkenes,dienes). Neoprene,Buna-$S$,and $PMMA$ (polymethyl methacrylate) are addition polymers formed via chain-growth polymerization. Glyptal is a polyester formed by the condensation polymerization of ethylene glycol and phthalic acid. Therefore,Glyptal is a step-growth (condensation) polymer,not a chain-growth polymer.
