Polyamides Higher Chemistry

Our Plan For Today We are going to learn about the structure of amines and how polyamides are formed by condensation polymerisation. Amines – What Are They? Amines structure Polyamides – Structures Nylon - Polyamide

Amines –NH2 The amines are a homologus series of carbon compounds all containing nitrogen atoms. The amine or amino group

Polyamide Formation Polyamides are formed when molecules with an amino group at one end and a carboxyl group at the other end combine.
