Vedclass · Answer

(A) . Natural rubber becomes soft and sticky at high temperature,not hard. So,statement $a$ is incorrect.$b$. Neoprene is formed by the polymerization of chloroprene ($2-$chloro$-1,3-$butadiene). So,statement $b$ is correct.$c$. Nylon $6,6$ is formed by the condensation polymerization of hexamethylenediamine and adipic acid,which contains amide linkages. So,statement $c$ is correct.$d$. Buna$-S$ is a copolymer formed from $1,3-$butadiene and styrene. So,statement $d$ is incorrect.Therefore,statements $b$ and $c$ are correct.
