Abstract: A composition is described comprising a styrene-isobutylene block copolymer; and at least one ethylenically unsaturated monomer. After curing the composition comprises polymerized units of the ethylenically unsaturated monomer. In some embodiments the ethylenically unsaturated groups are selected from (meth)acryl or vinyl ether. The composition is suitable for use as a (e.g. pressure sensitive) adhesive. Articles, methods of making an article, and methods of bonding are also described.

Abstract: An adhesive composition is described comprising a polyisobutylene polymer component; and up to 30 wt.-% of at least one aliphatic multifunctional component comprising at least two ethylenically unsaturated groups selected from (meth)acryl or vinyl ether. The monomer comprises a hydrocarbon moiety with greater than 12 contiguous carbon atoms. When the hydrocarbon moiety is branched, the hydrocarbon moiety comprises side chains with at least two carbon atoms. The aliphatic multifunctional component is sufficiently compatible such that crosslinked adhesive composition at a thickness of 20 microns has a haze of less than 3%. Also described are adhesive articles.
