WIPO Patent Application WO/2023/243908
Kind Code:
A1
Abstract:
The present invention relates to a thermoplastic resin composition, a method for preparing same, and a molded product manufactured therefrom and, more specifically, to a thermoplastic resin composition, a method for preparing same, and a molded product manufactured therefrom, the thermoplastic resin composition comprising: (A) an alkyl acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer comprising a seed prepared by polymerizing 35-58 wt% of alkyl acrylate and 42-65 wt% of an aromatic vinyl compound, a rubber core surrounding the seed and prepared by polymerizing 78-91 wt% of alkyl acrylate and 9-22 wt% of an aromatic vinyl compound, and a graft shell surrounding the rubber core and prepared by polymerizing 65-82 wt% of an aromatic vinyl compound, 12-30 wt% of a vinyl cyanide compound, and 3-15 wt% of alkyl acrylate; and (B) a non-graft copolymer comprising alkyl (meth)acrylate, an alkyl-substituted styrene-based compound, and a vinyl cyanide compound, wherein the average particle diameter and refractive index of each layer of the (A) graft copolymer are appropriately adjusted. According to the present invention, there is the effect of providing a thermoplastic resin composition having excellent transparency, glossiness, blackness, weather resistance, heat resistance and impact resistance, a method for preparing same, and a molded product manufactured therefrom.
