In A level chemistry curriculum, condensation polymerisation is the joining of two monomers with the elimination of a small molecule such as water or HCl
Polyesters
In A level chemistry, monomers must have a carboxyl group COOH, and a hydroxl group OH and can be made from 2 types of monomer units:
- one dicarboxylic acid (2 COOH groups) and one diol (2 OH groups)
- Bond forms between hydroxyl and carboxyl
- Ester linkage forms and eliminates water
- One type of monomer containing both a COOH and OH group
- Bond forms between hydroxyl of one and carboxyl of another
- ester linkage forms and water is eliminated
- In A level chemistry, condensation polymer refers to:
- COOH and -OH or -NH2 functional group
- 1 or 2 types of monomer
- Polyester or poly amide + water
- Addition polymer:
- C=C functional group
- 1 type of monomer
- Poly(alkane) produced
