THERMOPLASTIC RESIN COMPOSITION

摘要

The present invention provides a thermoplastic resin composition comprising (A) a graft copolymer containing a rubber having a small particle diameter, (B) a graft copolymer containing a rubber having a middle particle diameter, (C) an .alpha.-methylstyrene and/or maleimide-based copolymer having a reduced viscosity of from 0.45 to 1.2 and (D) a styrene-based copolymer having a reduced viscosity of from 0.20 to 0.45. The thermoplastic resin composition of the present invention is low in rigidity such as tensile strength, so ductile that its molded product shows no sharp edge on rupture cross-section upon collision, has a high resistance to thermal deformation and exhibits an excellent moldability.
