Addition Polymers

Synopsis: Introduces the molecular structure, reaction mechanisms, physical properties and manufacture of addition polymers. Discusses monomers and polymers and the process of addition polymerisation, using polyethene from ethene as an example, showing how the double bonds in monomers break to form polymers; the different properties of ethene polymers, including polyethene, and the formation of thermoplastics; examples of addition polymerisation, including polypropene, polyvinyl chloride (PVC) polyvinyl acetate (PVA) and polystyrene; the vulcanisation of rubber as an example of a thermosetting polymer; how some polymers (glues, resins, etc.) can be formed by mixing the polymer with a catalyst; how polymers can be modified to change their properties, by adding plasticisers, for example.
