PURPOSE: A thermoplastic resin composition is provided, which is improved in both the impact resistance and the fluidity. CONSTITUTION: The thermoplastic resin composition comprises 100 parts by weight of a material containing 15-40 parts by weight of an acrylonitrile-butadiene-styrene copolymer resin prepared by the emulsion graft polymerization using a rubbery polymer having an average particle size of 0.25-0.40 micrometers, and 60-85 parts by weight of a mixture of two kinds of styrene-acrylonitrile resins whose acrylonitrile content is 20-35 wt% and having a weight average molecular weight of 80,000-140,000; 1-5 parts by weight of ethylene bis stearamide; and 0.3-2 parts by weight of triphenyl phosphate. Preferably the acrylonitrile-butadiene-styrene copolymer has a degree of grafting of 40-90 %. |
