摘要：A thermoplastic resin composition is prepared by blending 50 - 95 wt. % of a copolymer (A) of 10 - 75 wt. % of α-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-bad rubber polymer and 15 -50 wt. parts of a vinyl monomer graft-polymerized onto the rubber polymer. The butadiene-bad rubber polymer includes 50 - 98 wt. % of butadiene, 2 - 50 wt. % of an aromatic polycyclic vinyl monomer reprented by a formula (I) below and 0 - 20 wt. % of a monomer copolymerizable therewith: wherein R denotes an optionally substituted biphenylyl or naphthyl group, and R₁ 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 becau 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.
