Chapter 31, Problem 31.43P
Interpretation Introduction

Interpretation: A stepwise mechanism for the anionic polymerization of styrene (CH2=CHPh) to form polystyrene [CH2CHPh]n, using BuLi as the initiator and CO2 as the electrophile that terminates the chain mechanism is to be drawn.

Concept introduction: An alkene (CH2=CHZ) that contains Z group as Ph,CO2R,COR or 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.
