Covulcanization of conjugated diene-containing butyl with halobutyl and butyl rubber

摘要

Blends of 5 to 95 wt. % conjugated diene-containing butyl rubber with 95 to 5 wt. % halobutyl or butyl rubber are capable of higher carbon black loading and have faster cure times, unusually high tensile strength and improved green strength. The blends may be cured with dienophilic compounds or sulfur-based cure packages.
