    摘要: Disclosed are a method of producing a graft copolymer, comprising polymerizing a vinyl monomer (B) containing a polyfunctional vinyl monomer (b1) in the presence of a polyorganosiloxane rubber (A) comprising more than 20% by mass of a toluene-insoluble matter, wherein a mass percentage of the polyfunctional vinyl monomer (b1) is 11 to 19% by mass based on 100% by mass of a total amount of the polyorganosiloxane rubber (A) and the vinyl monomer (B); a graft copolymer obtained by the method; a resin composition being prepared by blending the graft copolymer with a resin and having high impact resistance and heat resistance and sufficient flame retardancy; and a molded article obtained by molding the resin composition.

    摘要: The object of the present invention is to provide a silicone-based copolymer which has excellent long-term antifouling property even in a dry-wet alternate portion of a ship and the like or a portion thereof near the surface of water, is excellent also inmechanical strength and recoatability and exhibits high antifouling performance even if an antifouling agent is not added, and an antifouling coating composition containing the copolymer. The present invention provides, as the silicon-based copolymer, a metal-crosslinked organopolysiloxane-thio block vinyl copolymer [D] wherein an organopolysiloxane-thio block vinyl copolymer [C] having a carboxylic acid-containing vinyl copolymer block [A] formed from constitutional units derived from a polymerizable unsaturated carboxylic acid (a1) and constitutional units derived from at least one other polymerizable unsaturated monomer(a2) copolymerizable with the polymerizable unsaturated carboxylic acid, and a specific organopolysiloxane-thio block [B] is cross linked with a divalent metal [M].
