Adhesive comprising a poly (isobutylene) copolymer containing pendant free radically polymerizable quaternary ammonium substituent.

摘要

It describes an adhesive composition comprising a copolymer of isobutylene repeat units and alkene repeating units. At least a portion of the alkene repeat units is attached to the pendant nitrogen atom of the quaternary ammonium salts containing free radical polymerizable substituents. The adhesive may optionally contain tackifiers, unfunctionalized polyisobutylene polymer, plasticizer, and other components such as combinations thereof.BACKGROUND.
