Rayon is an example. A monomer is a chemical species that can be polymerised to make a polymer e.g. ethylene. A polymer is a chemical species made by joining together a whole swag of monomers via polymerisation. e.g. polyethylene. Polymerisation is the act of sticking together a bunch of monomers to make a polymer. From: Herbert ® 18/03/2002 18:57:16 Subject: re: Chemical Materials post id: 666035 DV... I think that definition for synthetic material is a bit too case-specific. A synthetic material is basically anything that is synthesised... made by human hands as opposed to a natural occurance This forum is un-moderated.
