Abstract: PURPOSE:To prepare the title resin compsn. giving a molded article with an excellent surface gloss and suitable as a molding material for an electrical part by mixing a resin compsn. comprising two specific graft copolymers with a specified amt. of a liq. polyorganosiloxane. CONSTITUTION:In the presence of a butadiene polymer latex having a mean polymer particle diameter of 0.12-0.2mum and such a distribution of polymer particle diameters that at least 80% of the particles satisfy the relation of the formula, a monomer mixture M comprising an arom. vinyl and(or) an alkyl ester of an unsatd. carboxylic acid and vinyl cyanide is copolymerized to give a graft copolymer A. Separately, in the presence of a butadiene polymer latex having a mean polymer particle diameter of 0.24-0.38mum, the monomer mixture M is polymerized to give a graft copolymer B. The graft copolymers A and B are mixed to give a resin compsn. in such a way that the butadiene polymer content derived from the graft polymer B is 1.5-5wt.% based on the compsn. and is 30wt.% or lower based on the butadiene polymer content due to the graft polymer A, and total butadiene polymer content in the compsn. is 10-30wt.%. 100 pts.wt. said compsn. is mixed with 0.01-0.5 pts.wt. liq. polyorganosiloxane, thus giving the title compsn.
