A polycarbonate resin composition, which exhibits not only an excellent balance among fluidity, rigidity, heat resistance, and impact resistance while maintaining flame retardance but also an excellent performance of recycling efficiency and a molded article thereof are provided. The polycarbonate resin composition contains a resin mixture of component (A) which is composed of (A-1) 10 to 100 mass % of an aromatic polycarbonate resin wherein dihydroxybiphenyl is used in a part of a divalent phenol as the raw material thereof and (A-2) 90 to 0 mass % of an aromatic polycarbonate resin other than the aromatic polycarbonate resin of component (A-1), and an amorphous styrene resin (B), in a mass ratio of component (A) to component (B) of 50:50 to 95:5. The molded article is an injection-molded article made of the polycarbonate resin composition.
提供了一种聚碳酸酯树脂组合物,它不仅在保持阻燃性的同时展现了流动性、刚度、耐热性和抗冲击性之间的优异平衡,而且具有出色的回收效率表现和由该聚碳酸酯树脂组合物制成的成型品。该聚碳酸酯树脂组合物包含组分(A)的树脂混合物,其中组分(A)由(A-1)芳香族聚碳酸酯树脂组成,其中二羟基联苯在部分二价酚原料中使用,并且(A-2)为除组分(A-1)芳香族聚碳酸酯树脂之外的芳香族聚碳酸酯树脂,以及非晶态苯乙烯树脂(B),组分(A)与组分(B)的质量比为50:50至95:5。成型品是由该聚碳酸酯树脂组合物制成的注塑成型品。
