Document Type and Number:

WIPO Patent Application WO/2022/091613

Kind Code:

A1

Abstract:

A thermoplastic resin composition containing 50-70 weight parts of a polycarbonate resin (A), 5-30 weight parts of a rubber-containing graft copolymer (B) obtained by graft copolymerizing 35-60 wt% of a monomer mixture containing at least an aromatic vinyl monomer (b) and a vinyl cyanide monomer (c) in the presence of 40-65 wt% of a diene rubber polymer (a), and 10-45 weight parts of a vinyl copolymer (C) obtained by copolymerizing an aromatic vinyl monomer and a vinyl cyanide monomer, and containing 1-5 weight parts of an acrylic block copolymer (D) relative to 100 total weight parts of the polycarbonate resin (A), rubber-containing graft copolymer (B), and vinyl copolymer (C). A thermoplastic resin composition having excellent fluidity, heat resistance, and impact resistance and capable of vastly reducing coating defects and a molded product can be obtained.
