热塑性树脂组合物的制造方法
摘要：
本发明提供阻燃性高、注射成型时具有高的流动性、成型品的耐冲击性得到提高的热塑性树脂组合物。一种热塑性树脂组合物的制造方法，具有使用挤出机将结晶性聚酯树脂50～80重量份和非晶性聚酯树脂20～50重量份熔融混炼而得到聚酯树脂混合物的工序(1)和将上述聚酯树脂混合物、聚碳酸酯树脂、阻燃剂、防滴剂以及增韧剂混合的工序(2)，上述挤出机的料筒温度为250～280℃。
摘要（英）：

Provided is a thermoplastic resin composition having high flame resistance and high fluidity during injection molding, and improved impact resistance in a molded article. A method for producing a thermoplastic resin composition, the method including the step (1) of obtaining a polyester resin mixture by melt-kneading 50 to 80 parts by weight of crystalline polyester resin and 20 to 50 parts by weight of amorphous polyester resin with an extruder, and the step (2) of mixing the polyester resin mixture, a polycarbonate resin, a flame retardant, a dripping inhibitor and a toughening agent, wherein the cylinder temperature of the extruder is 250 to 280 DEG C.
