Abstract
Presently described is an adhesive composition comprising at least one isobutylene polymer and an alkyl amine adhesion promoting agent. The alkyl amine is unreactive with respect to the isobutylene polymer. In favored embodiments, the alkyl amine adhesion promoting agent comprises an alkyl group having 6-24 carbon atoms. Further, the isobutylene polymer is a non-halogenated copolymer or homopolymer. Also described are adhesive articles a pressure sensitive adhesive, as described herein on a backing. The adhesive is particularly suitable for articles intended for use in a wet environment such as kitchen or bath articles.
