WIPO Patent Application WO/2019/066375

Kind Code:

A2

Abstract:

The present invention relates to a thermoplastic resin composition showing excellent transparency and whitening resistance. The thermoplastic resin composition of the present invention comprises: (A) a multi-layer structured graft copolymer; and (B) a thermoplastic copolymer, the multi-layer structured graft polymer (A) comprising: a conjugated diene-based rubber latex core having a weight average particle diameter of 500-2,000 Å; an intermediate layer; and a graft layer, wherein the glass transition temperature of the intermediate layer is 40°C or lower, the glass transition temperature of the graft layer is 80°C or higher, and the difference in refractive index between the graft copolymer (A) and the thermoplastic copolymer (B) is smaller than 0.01.
