Edexcel A-level Chemistry Condensation polymers

Condensation polymers

This page covers the following topics:

1. Condensation polymerisation and amino acids
2. Further condensation polymerisation
3. Definitions of polymer terms
4. Intermolecular forces

Amino acids can react by condensation polymerisation to form biological proteins.

Condensation polymerisation and amino acids

When dicarboxylic acid and diol monomers join through condensation polymrisarion, a polyester is formed.

Further condensation polymerisation

A polymer is a long chain molecules made up of many smaller molecules. Polyamides, polypeptides and polyesters are all types of polymers.

Definitions of polymer terms

Condensation polymers are made up of monomers connected through polar bonds: C-N and C-O.

Intermolecular forces
