Styrene

This is an interesting copolymer variant in that one of the ingredients was a polymer to begin with.

The result is a long chain of polybutadiene criss crossed with shorter chains of poly(styrene co acrylonitrile).

Graft copolymers Graft copolymers are a special type of branched copolymer in which the side chains are structurally distinct from the main chain.

Smaller amounts of butadiene are used to make the nylon intermediate, adiponitrile, by the addition of a molecule of hydrogen cyanide to each of the double bonds in a process called hydrocyanation developed by DuPont.

And because these materials are so prolific, because they're found in so many places, there's one other place you'll find this material, styrene, which is made from benzene, a known carcinogen.
