WIPO Patent Application WO/2021/045429

Kind Code:

A1

Abstract:

The present invention relates to a thermoplastic resin composition and a molded product thereof and, more specifically, to a thermoplastic resin composition and a molded product thereof, the thermoplastic resin composition comprising: 100 parts by weight of a base resin consisting of A-1) 10-30 wt% of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer comprising an acrylate rubber with an average diameter of 0.05-0.15 μm, A-2) 20-40 wt% of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer comprising an acrylate rubber with an average diameter of 0.3-0.5 μm, B) 0-35 wt% of an aromatic vinyl polymer, and C) 10-60 wt% of a polymethacrylate; and D) 0.5-10 parts by weight of a polyamide. According to the present invention, provided are: a low-gloss thermoplastic resin composition having mechanical properties, processability and the like, which are maintained so as to be at least equal to those of a conventional ASA-based resin, excellent weather resistance, a low surface roughness value so as to give an aesthetically soft feeling, and a uniform surface gloss; and a molded product thereof.
