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 ?m and 30-90% by mass of a synthetic rubber having a weight average particle diameter within the range of 0.2-0.4 ?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 ?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 ?m or more is 20% or more.

Abstract: PROBLEM TO BE SOLVED: To provide a copolymer having a high heat resistance and hardly exhibiting coloration; a heat-resistant resin composition prepared by compounding the copolymer with a rubber-reinforced styrene resin and excellent in impact resistance and moldability and also in clarity; and a molded item prepared from the same. SOLUTION: This copolymer consists of unsaturated carboxylic acid units, unsaturated alkyl carboxylate units, glutaric anhydride units represented by formula (1) (wherein R and R are each H or a 1-5C alkyl), and, if necessary, other monomer units. The copolymer contains the unsaturated carboxylic acid monomer units in a content of 2,000 ppm or lower and hence is excellent in heat resistance, hardly exhibiting coloration.
