Vedclass · Answer

(A) copolymer is a polymer formed from two or more different types of monomer units. Option $A$ represents Buna-$S$ (Styrene-Butadiene Rubber), which is formed by the copolymerization of $1,3$-butadiene $(CH_2=CH-CH=CH_2)$ and styrene $(C_6H_5CH=CH_2)$. Options $B$, $C$, and $D$ represent homopolymers: $B$ is Polytetrafluoroethene (Teflon),$C$ is Polychloroprene (Neoprene),$D$ is Polyvinyl chloride $(PVC)$. Therefore, the correct answer is $A$.
