    • A thermoplastic resin composition is prepared by blending 50-95 wt. % of a copolymer (A) of 10-75 wt. % of .alpha.-methyl styrene, 10-60 wt. % of methyl methacrylate, 5-35 wt. % of acrylonitrile and 0-20 wt. % of a monomer copolymerizable therewith; and 5-50 wt. % of a graft copolymer (B) comprising 50-85 wt. parts of a butadiene-based rubber polymer and 15-50 wt. parts of a vinyl monomer graft-polymerized onto the rubber polymer. The butadiene-based rubber polymer includes 50-98 wt. % of butadiene, 2-50 wt. % of an aromatic polycyclic vinyl monomer represented by a formula (I) below and 0-20 wt. % of a monomer copolymerizable therewith: ##STR1## wherein R denotes an optionally substituted biphenylyl or naphthyl group, and R.sub.1 denotes a hydrogen atom or a methyl group. The thermoplastic resin composition is provided with a good balance among heat-resistance, impact resistance, transparency and processability because the graft copolymer (B) using an aromatic polycyclic vinyl monomer shows a good impact resistance-modifying effect while retaining a relatively high refractive index and the copolymer (A) shows a good heat resistance and a relatively low refractive index.
