Abstract
A pressure sensitive adhesive composition is described comprising a polyisobutylene polymer having a first functional group and an acrylic polymer having a second functional group present in the acrylic polymer backbone. The first and second functional groups form a hydrogen bond. In some embodiments, the adhesive composition further comprises a crosslinker that covalently crosslinks the second functional group(s) present in the polymer backbone of the acrylic polymer. Also described are adhesive articles, such as a tape, methods of adhesively bonding, and methods of making a pressure sensitive adhesive.
