Butyl rubber is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as PIB or polyisobutene, (C 4 H 8) n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based.Butyl rubber is produced by polymerization of about 98% of isobutylene with about 2% of isoprene.Structurally, polyisobutylene resembles polypropylene, having two methyl groups substituted on every other carbon atom.utyl rubber has excellent impermeability, and the long polyisobutylene segments of its polymer chains give it good flex properties. The formula for PIB is: â(âCH 2 âC(CH 3) 2 â) n â. The formula for IIR is:
