RUBBER-REINFORCED THERMOPLASTIC RESIN COMPOSITION AND RESIN MOLDED ARTICLE

WIPO Patent Application WO/2013/132722

A1

A rubber-reinforced thermoplastic resin composition having: a dispersed phase that is composed of a graft copolymer (A) produced by the graft copolymerization of at least one monomer (b) selected from the group consisting of an aromatic vinyl monomer, a vinyl cyanide monomer, a (meth)acrylic acid ester monomer and other copolymerizable monomers in the presence of a rubbery polymer (a); and a continuous phase that is composed of a (co)polymer (B) produced by the (co)polymerization of at least one monomer (b) selected from the group consisting of an aromatic vinyl monomer, a vinyl cyanide monomer, a (meth)acrylic acid ester monomer and other copolymerizable monomers. The rubber-reinforced thermoplastic resin composition is characterized in that the rubbery polymer (a) has such weight fractions that particles each having a particle diameter of 0.05 μm or more and less than 0.2 μm are contained in an amount of 50 to 90 wt% and particles each having a particle diameter of 0.2 μm or more are contained in an amount of 10 to 50 wt%, the graft rate of the graft copolymer (A) is 70 to 150%, and the rubbery polymer (a) is contained in an amount of 5 to 24 parts by weight relative to 100 parts by weight of the rubber-reinforced thermoplastic resin composition.
