Document Type and Number:
WIPO Patent Application WO/2018/084558
Kind Code:
A3
Abstract:
The present invention relates to a thermoplastic resin composition, a method for preparing the same, and a molded product comprising the same and, more specifically, to a thermoplastic resin composition comprising: (A) 5-35 wt% of a first graft copolymer having an average particle diameter of 50-150 nm and comprising an acrylate-based rubber as a core; (B) 10-40 wt% of a second graft copolymer having an average particle diameter of greater than 150 nm and equal to or smaller than 800 nm and comprising an acrylate-based rubber as a core; (C) 5-15 wt% of an aromatic vinyl compound-vinyl cyan compound copolymer having a weight average molecular weight of 70,000-130,000 g/mol; (D) 20-50 wt% of an aromatic vinyl compound-(meth)acrylate-based compound copolymer having a weight average molecular weight of 65,000-100,000 g/mol; and (E) 0.1-7 wt% of a syndiotactic polystyrene-based resin. The present invention has effects of providing: a thermoplastic resin composition having low glossiness, excellent coloring property and pencil hardness, and improved abrasion resistance; a method for preparing the same; and a molded product comprising the same.
