ADHESIVES COMPRISING POLY(ISOBUTYLENE) COPOLYMERS COMPRISING PENDENT FREE-RADICALLY POLYMERIZABLE QUATERNARY AMMONIUM SUBSTITUENT

摘要

Adhesive compositions comprising a copolymer of isobutylene repeat units and alkene repeat units are described. At least a portion of the alkene repeat units are bonded to a pendent nitrogen atom of a quaternary ammonium salt comprising a free-radically polymerizable substituent. The adhesive optionally comprises other components such as tackifier, unfunctionalized polyisobutylene polymer, plasticizer, and combinations thereof.
