Usage
Polyisobutylene, sometimes called butyl rubber, and other times PIB, is a vinyl polymer. It’s very similar to polyethylene and polypropylene in structure, except that every other carbon is substituted with two methyl groups. It is made from the monomer isobutylene, by cationic vinyl polymerization.
