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.

Abstract: Compositions are described comprising at least 20 wt. % of block copolymer comprising polyvinyl aromatic end blocks and a polyisoprene midblock and at least one ethylenically unsaturated monomer comprising one or more groups selected from (meth)acryl or vinyl ether. In one embodiment, the monomer has a Log P according to Moriguchi's method of at least 2.2. In another embodiment, the monomer is a multifunctional aromatic ethylenically unsaturated monomer. The composition is typically a (e.g. pressure sensitive) adhesive. Also described are methods of making an article, adhesive articles, and methods of bonding.

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.
