Chapter 12, Problem 5QP

Interpretation Introduction

Interpretation:

The structure of the alternating copolymer of the given two compounds is to be represented.

Concept introduction:

Polymers are molecules of high molecular masses that are made up of repeating monomer units. Polymers are the backbone of four major chemical industries, viz., plastics, elastomers, fibers, and paints and varnishes.

On the basis of mode of polymerization, polymers have been classified into two subgroups, which are addition polymers and condensation polymers.

Addition polymers are formed when there is a movement of electrons from multiple bonds into new single bonds between molecules without elimination of small molecule.

Polymers that are formed by elimination of small molecules like ${\text{H}}_2\text{O}$ are condensation polymers.

Copolymers are polymers made from two or more different monomer units.

Alternative copolymers are of the type $-\text{A}-\text{B}-\text{A}-\text{B}-\text{A}-\text{B}-$.
