Chapter 31, Problem 31.33P

Interpretation Introduction

Interpretation: The structure of the polymer that results from anionic polymerization of p-trichloromethylstyrene $\left({\text{CCl}}_{\text{3}}{\text{C}}_{\text{6}}{\text{H}}_{\text{4}}\text{CH}={\text{CH}}_{\text{2}}\right)$ using ethylene oxide as the electrophile to terminate the chain is to be drawn.

Concept introduction: An alkene $\left({\text{CH}}_{\text{2}}=\text{CHZ}\right)$ that contains $\text{Z}$ group as $\text{Ph,}{\text{CO}}_{\text{2}}\text{R,}\text{COR}$ or $\text{CN}$, undergoes anionic polymerization to yield addition polymers. The initiator used in the reaction is an organolithium reagent. The reaction terminates, when an electrophile or acid is added.
