More Information
Summary:In one embodiment, an adhesive composition is described comprising a polyisobutylene polymer component, a styrene-isobutylene block copolymer, and optionally a tackifier. The polyisobutylene polymer component comprises one or more polyisobutylene polymers. The polyisobutylene polymer component has an average weight average molecular weight ranging from 100 g/mole to less than 15,000 g/mole. In some embodiments, the adhesive composition is a pressure sensitive adhesive.
