RUBBER-REINFORCED THERMOPLASTIC RESIN AND THERMOPLASTIC RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a rubber-reinforced thermoplastic resin which can give a molding excellent in impact resistance and weather resistance and excellent in surface appearance of the molding and to provide a thermoplastic resin composition containing the same. SOLUTION: This rubber-reinforced thermoplastic resin is obtained by polymerizing at least two monomer components selected from among aromatic vinyl compounds, vinyl cyanide compounds and (meth)acrylic esters in the presence of an ethylene/α-olefin copolymer rubber, wherein the mean particle diameter of the graft rubber particles of the resin is 0.2-0.8μm, and a composition prepared by mixing this resin with another thermoplastic resin is provided.
