Explanation Monomers combine to form polymers through different mechanisms. Polymers can be formed through am mechanism known as cationic polymerization. In the mechanism, the intermediate formed is a carbocation and through this intermediate polymer is formed. Polystyrene can be formed from the monomer styrene through cationic polymerization.

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

Chapter 27, Problem 26P

Interpretation Introduction

Interpretation:

The stability of the intermediate formed in the cationic polymerization of styrene to polystyrene has to be explained using resonance structures.
