Abstract
A process for producing an allylic alcohol functionalized butyl rubber involves contacting an epoxidized butyl rubber with benzoic acid, an analogue of benzoic acid or a C1-C7 alkanoic acid. The process and a polymer compound comprising the epoxidized butyl rubber and the benzoic acid, analogue of benzoic acid or a C1-C7 alkanoic acid provide a cost effective route to a polar functionalized butyl rubber, particularly to butyl rubber comprising allylic alcohol functional groups.
