Document Type and Number:
WIPO Patent Application WO/2021/054679
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition, a preparation method therefor, and a molded product manufactured therefrom and, more specifically, to a thermoplastic resin composition, a preparation method therefor, and a molded product manufactured therefrom, the thermoplastic resin composition comprising: 100 parts by weight of a base resin consisting of A-1) an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer comprising, as the core thereof, an acrylate rubber with an average diameter of 0.05-0.15 μm, A-2) an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer comprising, as the core thereof, an acrylate rubber with an average diameter of 0.3-0.6 μm, B-1) an aromatic vinyl polymer, and B-2) a heat resistant aromatic vinyl polymer; and C) 0.5-10 parts by weight of a polyolefin elastomer, wherein the heat deflection temperature (HDT) is 89°C or higher. According to the present invention, provided are: a thermoplastic resin composition comprising a predetermined additive that is less expensive than a conventional additive for chemical resistance, so as to satisfy both economic feasibility and chemical resistance, and having excellent heat resistance and impact resistance; a preparation method therefor; and a molded product manufactured therefrom.
