    Abstract: Pressure sensitive adhesive compositions are described comprising at least one low Tg ethylenically unsaturated monomer, and at least one silsesquioxane polymer crosslinker comprising a plurality of ethylenically unsaturated groups. The low Tg ethylenically unsaturated monomer typically has a Tg no greater than 10° C. In some embodiments, the composition comprises at least 50, 55, 60, 65, or 70 wt-% of low Tg ethylenically unsaturated monomer. The low Tg ethylenically unsaturated monomer is typically an alkyl (meth)acrylate comprising 4 to 20 carbon atoms. In another embodiment, an adhesive composition is described comprising a syrup. The syrup comprising i) a free-radically polymerizable solvent monomer; ii) a solute (meth)acrylic polymer comprising polymerized units derived from one or more alkyl (meth)acrylate monomers, and iii) at least one silsesquioxane polymer crosslinker comprising a plurality of ethylenically unsaturated groups. The free-radically polymerizable solvent monomer, polymerized units of the solute (meth)acrylic polymer, or a combination thereof comprise a low Tg ethylenically unsaturated monomer. Also described are pressure sensitive adhesive articles and method of preparing adhesive articles.

    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.
