Butyl rubber, a process for preparing it, and rubber products, compositions and uses thereof, and automotive tire innerliners, inner tubes and curing bladders

摘要

Butyl rubber, a process for producing the same, a composition containing butyl rubber, and a butyl rubber, wherein the butyl rubber has a structural unit derived from isobutylene, a structural unit derived from a conjugated diene, Selected from the group consisting of aryl olefin-derived structural units, wherein at least a portion of the conjugated diene is at least isoprene. Further, an automobile tire inner liner made of butyl rubber, a tire inner tube, and a curing bladder are provided. The butyl rubber has good processability, composability, die swell ratio, integrated mechanical properties, and especially high tear strength. The butyl rubber can effectively lower the power consumption in the processing and compounding processes, and the manufactured products have good dimensional stability and usability.
