Abstract

PURPOSE: To obtain titled resin having excellent surface gloss, weather resistance, heat resistance, impact resistance, etc., by graft polymerizing an alkenyl aromatic monomer and an unsaturated dicarboxylic acid anhydride-containing monomer component in the presence of an ehylene-propylene rubber.
CONSTITUTION: A thermoplastic resin is produced by dissolving the total ethylene- propylene rubber in a monomer consisting mainly of an alkenyl aromatic monomer, e.g., styrene, if necessary, adding a solvent which dissolves the rubber, continuously adding an unsaturated dicarboxylic acid anhydride, e.g., maleic anhydride, so that the ratio to the anhydride is kept substantially constant during the polymerization, and copolymerizing the reaction mixture so that the total resin composition obtained by the polymerization contains 20W30wt% rubber and 5W35wt% unsaturated dicarboxylic acid anhydride. Thus, an impact-resistant resin having excellent resistance to heat and weather, and good surface gloss and appearance is obtained by polymerizing so as to reduce the amount of alternating chains of the alkenyl aromatic monomer and the unsaturated dicarboxylic acid anhydride.
