Butyl rubber

Vedclass · Answer

(A) The copolymerization of isobutylene ($2$-methylpropene) with a small amount of isoprene ($2$-methyl-$1,3$-butadiene) in the presence of anhydrous $AlCl_{3}$ at low temperatures (around $-100^{\circ} C$) yields Butyl rubber.The chemical reaction is as follows:$n \ CH_{2}=C(CH_{3})_{2} + n \ CH_{2}=C(CH_{3})-CH=CH_{2}$ $\xrightarrow{AlCl_{3}} -[CH_{2}-C(CH_{3})_{2}-CH_{2}-C(CH_{3})=CH-CH_{2}]_{n}-$Thus,the correct option is $A$.

Identify the polymer obtained by heating $n$ moles of isobutylene with $n$ moles of isoprene at $100^{\circ} C$ in the presence of anhydrous $AlCl_{3}$.
