Chapter 21, Problem 21.46AP

Interpretation Introduction

(a)

Interpretation:

The design for preparation of nylon-$4,6$ from dicarboxylic acid containing six or lesser carbon atom is to be drawn.

Concept introduction:

Acids can be substituted with amino group to get amides. These amide units join to polymerize and form nylon $-4,6$. Polymerization is joining of small molecular units, to form a large structure known as polymer. Small molecular units are monomers. They add up to form a chain or a three dimensional structure of the polymer.

Interpretation Introduction

(b)

Interpretation:

The design for preparation of polyester from dicarboxylic acid containing six or lesser carbon atom is to be drawn.

Concept introduction:

The polymers are a type of macromolecules which are formed by repeated units of monomers. The polymer can be formed by different polymerization methods such as free radical polymerization and condensation polymerization. Polyesters are formed by condensation polymerization between and dicarboxylic acid and diol.
