聚碳酸酯树脂颗粒的制造方法
摘要：
一种聚碳酸酯树脂颗粒的制造方法，其是含有作为(A)成分的聚碳酸酯树脂、作为(B)成分的硅酮化合物和作为(C)成分的碳数为12～22的脂肪族羧酸与甘油的酯的聚碳酸酯树脂颗粒的制造方法，其中，该制造方法包括如下工序：将含有上述(A)成分、(B)成分和(C)成分的配合物导入挤出机，在该挤出机的出口处的熔融树脂温度为260℃以上且325℃以下的条件下，将上述配合物在上述挤出机内进行熔融混炼，通过挤出成形得到聚碳酸酯树脂颗粒，相对于上述(A)成分100质量份，所得到的聚碳酸酯树脂颗粒含有0.01质量份以上且0.25质量份以下的上述(B)成分和0.015质量份以上且0.25质量份以下的上述(C)成分。
摘要（英）：

This method is for manufacturing polycarbonate resin pellets containing a polycarbonate resin as component (A), a silicone compound as component (B), and esters of glycerin and an aliphatic carboxylicacid having 12-22 carbon atoms as component (C). The method involves a step in which a mixture containing the component (A), the component (B) and the component (C) is introduced into an extruder, the mixture is melted and kneaded inside of the extruder under the condition that the molten resin temperature is 260 DEG C-325 DEG C at the exit of the extruder, and polycarbonate resin pellets are obtained by extrusion molding. Per 100 parts by mass of the component (A), the obtained polycarbonate resin pellets contain 0.01-0.25 parts by mass of the component (B) and 0.015-0.25 parts by mass of the component (C).
