Polymers

KEY WORDS

Monomer - A simple molecule which can be joined together, in large numbers, to form a long chain polymer

Addition polymer - A long chain molecule produced by joining together a large number of simple molecules (monomers). The monomers used are alkene, or alkene derivitive.

Polymerisation - This is the process in which large numers of simple molecules are joined together to form long chain polymers. Usually around 5 - 10 thousand monomers.

Examples of polymers - polychloroethene (PVC)

                                   - polyphenylethene (polystyrene)
