The present invention relates to a polymer composite containing at least one carboxylated nitrile rubber polymer, that is optionally hydrogenated, and at least halogenated butyl rubber, a process for preparing said polymer composite wherein at least one carboxylated nitrile rubber polymer, that is optionally hydrogenated, and at least one halogenated butyl rubber are mixed and a shaped article containing at least one carboxylated nitrile rubber polymer, that is optionally hydrogenated, and at least one halogenated butyl rubber, as well as a method of increasing the cross-linking density of a halogenated butyl rubber by admixing said halogenated butyl rubber with at least one, optionally hydrogenated, carboxylated nitrile rubber polymer, optionally at least on cross-linking agent, and optionally a filler and curing the compound. |
