Document Type and Number:
WIPO Patent Application WO/2023/243909
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition, a preparation method therefor, and a molded product manufactured therefrom. More specifically, the present invention relates to a thermoplastic resin composition, a preparation method therefor, and a molded product manufactured therefrom, wherein the thermoplastic resin composition comprises (A) an alkyl acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer comprising: a polymer seed containing and polymerized with 45 to 72 wt% of an alkyl acrylate and 28 to 55 wt% of an aromatic vinyl compound; a rubber core surrounding the polymer seed and containing and polymerized with 78 to 91 wt% of an alkyl acrylate and 9 to 22 wt% of an aromatic vinyl compound; and a graft shell surrounding the rubber core and containing and polymerized with 65 to 82 wt% of an aromatic vinyl compound, 12 to 30 wt% of a vinyl cyanide compound, and 3 to 15 wt% of an alkyl acrylate, and (B) a non-graft copolymer including an alkyl (meth)acrylate, an aromatic vinyl compound, a vinyl cyanide compound, and an imide-based compound, wherein the average particle diameter and refractive index of each layer in the graft copolymer (A) are appropriately controlled. The present invention has the effect of providing a thermoplastic resin composition superb in terms of transparency, glossiness, heat resistance, weather resistance, and impact resistance, a preparation method therefor, and a molded product manufactured therefrom.
