A thermal-resistant styrene resin composition comprising (1) 100 parts by weight of thermal-resistant styrene copolymer composed of a continuous matrix phase of styrene copolymer (A) having imido group and 5 to 45 wt.% relative to the resin composition of rubber particles (B) dispersed in the continuous matrix phase; and (2) 0.1 to 5 parts by weight of low molecular weight polyolefine (C) having a viscosity average molecular weight of 500 to 10,000, the low molecular weight polyolefine (C) being low molecular weight polyethylene; the styrene copolymer (A) having imido group being obtained by polymerizing styrene monomer 89 to 20 wt.%, acrylonitrile monomer 10 to 50 wt.%, maleic imide monomer 1 to 30 wt.% and other copolymerizable monomer 0 to 40 wt.%, the rubber particles (B) having a weight average diameter of 0.05 to 0.8 um, and the total amount of dimers and trimers made from styrene monomer and/or acrylonitrile monomer in the thermal-resistant resin composition being less than 20,000 ppm.
