Title:
THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/195798
Kind Code:
A1
Abstract:
A thermoplastic resin composition that contains: a particulate graft copolymer that is formed from a seed, a core layer, and a shell layer; and a matrix resin. The matrix resin includes an acrylonitrile-styrene resin. The difference between the refractive index of the seed and the refractive index of the matrix resin is at least 0.07. The core layer comprises a polymer that has a cross-linked structure and is a polymer of a monomer component that includes an acrylic acid ester. The graft copolymer satisfies the following expressions. In the expressions, r1 is the radius (nm) of the seed, and r2 is the radius (nm) of a particle formed from the seed and the core layer. 300≤2×r2≤700; 40≤r2-r1≤210.
