异丁烯基弹性体包括IIR、卤化丁基橡胶(HIIR)及其星形支化产品。IIR和HIIR(BIIR和CIIR)硫化与通用橡胶不同。IIR分子主链的不饱和度约为2%。HIIR在丁基主链上引入溴或氯,提高了聚合物主链上异戊二烯单元的反应活性。由于主链具有极低的不饱和度,使IIR和HIIR在许多工业领域得到
Isobutylene based elastomers include IIR, halogenated butyl rubber (HIIR) and their star-branched products. IIR and HIIR (BIIR and CIIR) are vulcanized differently from general purpose rubbers. The unsaturation of the IIR backbone is about 2%. HIIR introduces bromine or chlorine on the butyl backbone to increase the reactivity of isoprene units on the polymer backbone. Due to the extremely low unsaturation of the backbone, IIR and HIIR are available in many industrial fields
