Students learn to identify the following as
commercially significant
monomers:
- vinyl chloride - styrene by both their systematic and common names Polyethene (polyethylene) and polypropene (polypropylene) are two of the most common synthetic polymers. It is estimated that worldwide about 5 kg of polyethene is produced per person per year. Vinyl chloride and styrene, both produced from ethene, are the monomers for some more polymers of global importance - PVC (poly(vinylchloride)) and poly(styrene).
These are all polymers that are formed by addition polymerisation. It's interesting to note that although the names of these monomers (styrene,
vinyl chloride and acrylonitrile) look like they are trivial names, they
are in fact the correct, formal names approved by IUPAC for these molecules. This is an indication of the innate conservatism of polymer chemists and their disproportionate representation in the councils of the great.
