丁基橡胶 Butyl rubber

(重定向自Polyisobutylene)
丁基橡胶所制成的手套,适合于处理化学药品等腐蚀性物质

丁基橡胶英语:Butyl rubber,常用缩写是IIR ,代表Isobutylene Isoprene Rubber)是一种合成橡胶,是异丁烯和少量异戊二烯的共聚物,其中异戊二烯占0.6%到3%,根据异戊二烯的含量分成4-5个商品等级,丁基橡胶的结构如右图所示:

由于甲基分布在碳链两侧,使丁基橡胶具有优秀的抗气体透过性,通过加入异戊二烯的结构单元,改善了主链的柔顺性。

Butyl rubber 丁基橡胶

(重定向自Polyisobutylene)
Butyl rubber gloves

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.
