A polycarbonate resin composition comprising a polycarbonate copolymer (A), glass (B) and a polycarbonate resin (C), wherein the difference (absolute value) in refractive index between a mixture of the copolymer (A) with the resin (C) and glass (B) is 0.01 or less. A process for producing a polycarbonate resin composition which comprises kneading a polycarbonate copolymer (A), glass (B) and a polycarbonate resin (C) together and adjusting the difference (absolute value) in refractive index between a mixture of the copolymer (A) with the resin (C) and glass (B) to 0.01 or less by suitably selecting the kind and amount of each comonomer unit of the copolymer (A). This resin is excellent in transparency and flame retardation and can be utilized as the material of various molded articles widely used in the fields of electric and electronic appliances and automobiles.
一种由聚碳酸酯共聚物(A)、玻璃(B)和聚碳酸酯树脂(C)组成的聚碳酸酯树脂组合物,其中共聚物(A)与树脂(C)和玻璃(B)的混合物之间的折射率差(绝对值)为 0.01 或更小。一种生产聚碳酸酯树脂组合物的工艺,包括将聚碳酸酯共聚物(A)、玻璃(B)和聚碳酸酯树脂(C)揉捏在一起,并通过适当选择共聚物(A)中各共聚单体单元的种类和数量,将共聚物(A)与树脂(C)和玻璃(B)的混合物之间的折射率差(绝对值)调整到 0.01 或以下。这种树脂具有良好的透明度和阻燃性,可用作广泛应用于电子电器和汽车领域的各种模塑制品的材料。
