Chapter 31, Problem 31.42P

Interpretation Introduction

Interpretation: The reason corresponding to the fact that the acrylonitrile $\left({\text{CH}}_{\text{2}}=\text{CHPh}\right)$ undergoes cationic polymerization more slowly than but $\text{-3-}$ enenitrile $\left({\text{CH}}_{\text{2}}={\text{CHCH}}_2\text{CN}\right)$ is to be stated.

Concept introduction: The cationic polymerization is a chain growth polymerization. In this reaction, a charge is transferred to a monomer by the cationic initiator. After the transfer of charge, the monomer becomes reactive. This monomer gain reacts with other monomers in a similar way and forms a polymer.
