Chapter 21, Problem 21.12TC

Interpretation Introduction

Interpretation:

The starting reactants of the following condensation polymer are to be identified.

Concept introduction:

Step-growth polymers are the polymers that are synthesized by the stepwise reaction of monomer unit with the growing chain. Condensation reactions are employed for the synthesis of the step-growth polymerization reaction.

The condensation reaction of the dicarboxylic acid and dialcohol are employed for the synthesis of polyesters. The water molecule is eliminated in the reaction. The general reaction for the synthesis of two repeating units of the polymer is,

Here, R is an alkyl group.
