Abstract

Disclosed are reactive functionalized, PIB grafted polymers having an architecture of one or more pendent polyisobutylene moieties grafted on to an organic backbone, wherein the backbone is not polyisobutylene and contains at least one telechelic, reactive functionality. Also a process for making the reactive functionalized, PIB grafted polymer s and curable compositions comprising the reactive functionalized, PIB grafted polymers.
