聚碳酸酯树脂组合物及光学用成形品
Abstract:
本发明提供一种聚碳酸酯树脂组合物，其特征在于，其是相对于聚碳酸酯树脂(A)100重量份配合熔融粘度调节剂(B)0.005～3.0重量份及亚磷酸酯系化合物(C)0.005～1.0重量份而成的聚碳酸酯树脂组合物，将在测定温度220℃、剪切速度10sec-1时的熔融粘度设为η时，聚碳酸酯树脂组合物的熔融粘度η1与聚碳酸酯树脂(A)的熔融粘度η2之比η1/η2满足0.45≤η1/η2≤0.95。
Abstract(English):

The invention provides a polycarbonate resin composition. The polycarbonate resin composition is obtained by blending, with respect to 100 pts.wt. of a polycarbonate resin (A), 0.005 to 3.0 pts.wt. of a melting viscosity modifier (B) and 0.005 to 1.0 pt.wt. of a phosphorous ester compound (C), and has a ratio eta 1/ eta 2 of melting viscosity of the polycarbonate resin composition eta 1 to melting viscosity eta 2 of the polycarbonate resin (A) satisfying 0.45<= eta 1/ eta 2<=0.95, where eta is melting viscosity at a measurement temperature of 220 DEG C and shearing rate of 10 sec.
