Abstract: The present invention addresses the problem of providing a natural rubber-containing thermoplastic resin composition which uses a natural rubber latex and has physical properties achieving excellent balance among impact resistance, fluidity and color tone, without requiring a complicated deproteinization process for natural rubbers. A solution of the problem is a natural rubber-containing thermoplastic resin composition which contains a graft copolymer (A) that is obtained by graft polymerizing a vinyl monomer mixture (a), which contains at least an aromatic vinyl monomer, to a rubber polymer (R) that is formed of 10-70% by mass of a natural rubber having a weight average particle diameter within the range of 0.3-1.2 [mu]m and 30-90% by mass of a synthetic rubber having a weight average particle diameter within the range of 0.2-0.4 [mu]m. This natural rubber-containing thermoplastic resin composition is characterized in that: the natural rubber particles contain natural rubber particles having particle diameters of 1.0 [mu]m or more in an amount of 5% by mass or more; and the inner graft rate of the rubber polymer (R) particles having particle diameters of 1.0 [mu]m or more is 20% or more.

Abstract: A thermoplastic resin composition comprising a graft copolymer (I) which is produced by carrying out the graft polymerization of a monomer mixture (B) comprising an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of an acrylic rubbery polymer (A) and a vinyl copolymer (II) which is produced by carrying out the copolymerization of an aromatic vinyl monomer with a vinyl cyanide monomer, wherein the ratio of the content of the former copolymer to that of the latter copolymer is (30 to 70 parts by weight) : (70 to 30 parts by weight), the graft copolymer (I) has such a property that the ratio (i.e., (±)/(²)) of the gel swelling degree (±) of the acrylic rubbery polymer (A) in toluene to the grafting ratio (²) of the graft copolymer (I) is 0.4 to 2.0, and the thermoplastic resin composition has such a structure that particles of the graft copolymer (I) are aggregated in the thermoplastic resin composition. From the thermoplastic resin composition, a molded article having excellent fluidability, weather resistance and impact resistance can be produced.
