摘要： A silicone hybrid pressure sensitive adhesive composition that cures to form a silicone hybrid pressure sensitive adhesive contains a polydiorganosiloxane having reactive groups. The reactive groups include a silicon bonded (meth)acryloxyalkyl-functional group in a pendant position and a silicon bonded aliphatically unsaturated hydrocarbon group. An adhesive article, such as a tape, can be formed by coating the silicone hybrid pressure sensitive adhesive composition on a surface of a substrate and curing said composition via hydrosilylation reaction (B-staged cure) to form a silicone hybrid pressure sensitive adhesive layer on the surface. The silicone hybrid pressure sensitive adhesive layer contains (meth)acryloxyalkyl-functional groups, which can further react and crosslink via exposure to UV radiation (C-staged cure).

摘要： A polydiorganosiloxane having both a silicon bonded aliphatically unsaturated group and a silicon bonded poly(meth)acrylate polymer or copolymer, and method for preparation of this polydiorganosiloxane are disclosed. The method preserves the aliphatically unsaturated groups when grafting the poly(meth)acrylate to the polydiorganosiloxane. This polydiorganosiloxane is useful in hydrosilylation reaction curable compositions, such as pressure sensitive adhesive compositions.
