Abstract
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.
