GRAFT COPOLYMERS EXCELLENT IN PROPERTY TO BE COLORED AND THERMOPLASTIC RESIN COMPOSITIONS WITH THE SAME

摘要

A graft copolymer obtained by graft--polymerizing one or more kinds of vinyl monomer onto a compound rubber in which a modified polyorganosiloxane rubber obtained by radical polymerization of one or more kinds of monomer selected from the group consisting of a polyfunctional unsaturated compound having at least one (meth)acryloyloxy group and a polyfunctional unsaturated compound having a cyanuric acid or isocyanuric acid skeleton in the presence of a polyorganosiloxane rubber, and a polyalkyl (meth)- acrylate rubber have been inseparably entangled with each other. The graft copolymer of the present invention is excellent in a property to be colored with pigments.
