This booklet contains practical experiments exploring plastics and polymerisation. The text starts with an introduction which explains the types of polymerisation (addition and condensation) and plastics (thermoplastic and thermosetting) and their molecular compositions. It also looks at the effects of heat on weak intermolecular forces.
