PURPOSE: A thermal plastic resin composition is provided to have excellent impact resistance, rigidity, and weatherability by adding styrene-acrylonitrile resin and filler to the hydrogenated core-shell graft copolymer. CONSTITUTION: A thermal plastic resin composition comprises 20-40 parts by weight of hydrogen-addition modified core-shell graft copolymer, 60-80 parts by weight of styrene-acrylonitrile resin of which glass transition temperature is 60°C or more, and weight average molecular weight is 100,000-180,000, and 1-3 parts by weight of CaCO3, based on the sum of the 100,0 parts by weight the sum of the copolymer and the resin. The hydrogenated core-shell graft copolymer is obtained by hydrogenation by adding hydrazine, peroxide based compound and acid catalyst.
