Thermoplastic resin composition and molded products thereof

摘要

A thermoplastic resin composition according to the present invention is characterized by comprising: (A) a polycarbonate resin; and (B) a biphenyl group-containing (meth)acrylic copolymer. As such, the refractive index of the biphenyl group-containing (meth)acrylic copolymer (B) can be approximately from 1.495 to 1.640. The thermoplastic resin composition exhibits superior balance of material properties such as impact strength, internal scratch resistance, transparency, thermal resistance and appearance.
