Abstract: 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.

Abstract: Adhesive composition are described comprising the reaction product of at least one halogenated copolymer of isobutylene wherein halogen atoms of the copolymer are replaced by a polyamine having a melting point greater than 25° C., thereby crosslinking the copolymer. The isobutylene copolymer comprises halogenated repeat units derived from isoprene, butadiene, para-alkyl styrene, or a combination thereof. The adhesive composition comprises a copolymer of isobutylene repeat units and second repeat units selected from alkene repeat units, para-methyl styrene repeat units, or a combination thereof wherein at least a portion of the second repeat units are directly bonded to one another with a polyamine crosslinker having a melting point greater than 25° C. Also described are adhesive articles, such as tapes, comprising such adhesives.

Abstract: Adhesive compositions are provided that include a crosslinked silicone gel, a hydrophilic component dispersed in the silicone gel, and an antimicrobial agent dispersed in the silicone gel. The adhesive composition is readily applied to (and removed from) skin, and has desirable hydrophilic and antimicrobial properties. Advantageously, the hydrophilic component in the cross-linked silicone gel is not readily extractable (e.g., into a pH 7 buffer). Surprisingly, the combination of hydrophilic component with antimicrobial agent in the crosslinked silicone gel can provide a synergistic level of antimicrobial activity.

Abstract: A curable composition comprising a silicone, a halomethyl-1,3,5-triazine and optionally a silicate tackifier is disclosed. The compositions are useful in the preparation of pressure-sensitive adhesives and release coatings.

Abstract: An adhesive composition is described comprising a tackifier and at least one grafted isobutylene copolymer. The grafted isobutylene copolymer has the formula: R1—(R2—Z) wherein R1 represents an isobutylene copolymer, R2 is a covalent bond or multivalent alkylene or arylene, and Z is a grafted polymer. Z is typically a homopolymer of copolymer comprising alkene repeat units, aralkylene repeat units, or a combination thereof. Also described are adhesive coated articles, methods of making adhesive coated articles, and grafted isobutylene polymers.
