==Key Stage 4==
===Meaning===
[[Polymerisation]] is a [[Chemical Reaction|chemical reaction]] in which small [[molecule]]s known as [[monomer]]s [[Chemical Reaction|react]] to form a [[polymer]].
===About Polymerisation===
[[Polymerisation]] may happen between:
*Identical [[monomer]]s - [[Alkene]]s to Polyalkenes
*Two different [[monomer]]s with complimantary [[Functional Group|functional groups]] at each end. - [[Ester]]s to [[Polyester]]s
*Several different [[monomer]]s of a [[Homologous Series|homologous series]] - [[Peptide]]s to [[Polypeptide]]s.
