1. Polyamides Higher Chemistry

2. 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

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

4. Copy and Complete Go down to hexylamine with 6 carbon atoms

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

6. Individual Tasks • Stick both parts of appendix 2.19 into your jotter. • Read through the information on how nylon is formed (polyamides continued) • Turn to page 26 of your work booklets – Answer the questions in your rough notes jotters.
