ABSTRACT:
A polyorganosiloxane graft copolymer obtained by graft-polymerizing one or more kinds of monomer which have an ethylenically unsaturated bond and contain at least an epoxy group-containing vinyl monomer onto a compound rubber in which a polyorganosiloxane rubber and a polyalkyl (meth)acrylate rubber have been inseparably united with each other, and in which the component derived from the epoxy group-containing vinyl monomer occupies a proportion of 1 to 30 wt. % of the whole graft copolymer. This polyorganosiloxane graft copolymer is excellent in impact resistance, low-temperature characteristics and weather resistance, and also excellent in the bond strength to paint film applied thereto. This graft copolymer is also useful as adhesives, and particularly it exhibits excellent adhesion performance in depositing aromatic polymers such as polyesters (e.g. polyethylene terephthalate), polyphenylene oxides, polyphenylene sulfides, etc.
