The present invention relates to an acrylonitrile-acrylate-styrene graft copolymer, which is a copolymer comprising at least one compound selected from the group consisting of an aromatic vinyl compound, a vinyl cyan compound, and an alkyl (meth) acrylate compound; A core surrounding the seed and comprising an alkyl acrylate; And a shell which surrounds the core and comprises at least one compound selected from the group consisting of an aromatic vinyl compound, a vinyl cyan compound, and an alkyl (meth) acrylate compound, and has a structure in which the thickness and refractive index of each layer are appropriately controlled, Nitrile-acrylate-styrene graft copolymer, and a thermoplastic resin composition containing the same. In the acrylonitrile-acrylate-styrene graft copolymer according to the present invention, the seed refractive index is made close to the refractive index of the target matrix while maintaining the existing impact properties in consideration of the refractive index of the target matrix polymer, And the appearance of the thermoplastic resin is excellent when the morphology of the core having a large refractive index difference is controlled. |
