Title:
耐熱・耐塗装性熱可塑性樹脂組成物
Document Type and Number:
Japanese Patent JP6984585
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a thermoplastic resin composition which is resistant to thermal and impact shock, and with which the generation of swelling defects (blister) is suppressed during painting. The thermoplastic resin composition contains: a rubber-containing graft copolymer (A); a vinyl-based copolymer (B) comprising a vinyl cyanide-based monomer (i) and an aromatic vinyl-based monomer (ii); and a heat-resistant vinyl-based copolymer (C) comprising an aromatic vinyl-based monomer (ii) and a maleimide-based monomer or α-methylstyrene monomer (iii), wherein the vinyl-based copolymer (B) contains vinyl-based copolymers (B-1) and (B-2), the vinyl-based copolymer (B-1) having a weight average molecular weight of 250,000-400,000 and containing 25-33 wt% of the vinyl cyanide-based monomer (i), and the vinyl-based copolymer (B-2) having a weight average molecular weight of 80,000-100,000 and containing at least 15 wt% and less than 25 wt% of the vinyl cyanide-based monomer (i).
