Butyl Rubber
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, (C4H8)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. Polyisobutylene is a colorless to light yellow viscoelastic material.
It is generally odorless and tasteless, though it may exhibit a slight characteristic odor.
