Copolymers
Some of the most commercially important addition polymers are the copolymers. There are polymers made by polymerising a mixture of two or more monomers. An example is styrene-butadiene rubber (SBR) - which is a copolymer of butadiene and styrene. Most is vulcanised and used in tyre production - though some is used for bubble-gum (unvulcanised form).
