The objective of the present invention is to provide a thermoplastic resin composition excelling in translucency, impact resistance, heat resistance and fluidity, particularly a thermoplastic resin composition that in the production of thermoplastic resin molded items through extrusion processing, molding processing, etc., permits a wide tolerance range of processing conditions, such as low susceptibility to quality deterioration by thermal history, excelling in translucency, impact resistance, heat resistance and fluidity; and a molding thereof. The present composition comprises a rubber-reinforced resin consisting of a rubber-reinforced copolymeric resin obtained by polymerization of a vinyl-based monomer including an aromatic vinyl compound in the presence of a rubbery polymer having refractive index in the range from 1.520-1.580, or a mixture of this rubber-reinforced copolymeric resin and a (co)polymer of the above vinyl-based monomer, and a polycarbonate resin in specified ratio, and further comprises a phosphoric compound.
本发明的目的是提供一种半透明性、抗冲击性、耐热性和流动性优异的热塑性树脂组合物,特别是在通过挤压加工、模塑加工等生产热塑性树脂模塑制品时,允许加工条件的宽容许范围,如不易因热历史而导致质量下降,半透明性、抗冲击性、耐热性和流动性优异的热塑性树脂组合物;及其模塑。本组合物包括一种橡胶增强树脂,由乙烯基单体(包括芳香族乙烯基化合物)在折射率在 1.520-1.580 之间的橡胶聚合物存在下聚合而成的橡胶增强共聚物树脂,或这种橡胶增强共聚物树脂与上述乙烯基单体的(共)聚合物按特定比例混合而成的混合物,以及一种聚碳酸酯树脂组成,还包括一种磷化合物。
