(a)

Interpretation Introduction

Interpretation:

The structure of Nomex is to be drawn.

Concept introduction:

The polymerization process in which molecules join together with loss of water or methanol is known as condensation polymerization.

The synthetic fibre, Nomex is a polyamide and flame-resistant material that is used to make fire-fighting equipments and clothing. It has very good thermal, chemical and radiation resistance.
