丁基橡胶(IIR)是世界上第四大合成橡胶(SR)胶种,由异丁烯和异戊二烯在Friedel-Craft催化剂作用下进行阳离子聚合反应而生成。分子结构为规整的线形结构,外观为白色或淡黄色晶体,无臭无味,玻璃化温度很低,不溶于乙醇和丙酮。
Butyl rubber (IIR) is the fourth largest synthetic rubber (SR) in the world and is produced by the cationic polymerization of isobutylene and isoprene under the Friedel-Craft catalyst. The molecular structure of a structured linear structure, the appearance of white or light yellow crystals, odorless, low glass transition temperature, insoluble in ethanol and acetone.
