    • A melt extrusion processing method of a thermoplastic resin, wherein a thermoplastic resin having a flow temperature of 200.degree. C. or higher is subjected to extrusion processing using a melt kneading type extruder in which a vent port is provided at a downstream position by length L from the most upper stream portion of a melt kneading type extruder screw and L/D is from 4 to 18 (wherein D indicates the screw diameter and D and L are in the same scale unit), while continuously sucking from the said vent port at a reduced pressure of lower then 660 mmHg.The invention provides a method which causes little resin degradation in an extruder to give an extruded article containing small amounts of discolored and degraded materials even when the processing is conducted for a relatively long time.
    • 使用熔融捏合型挤出机对流动温度为200℃以上的热塑性树脂进行挤出加工的热塑性树脂的熔融挤出加工方法,其中在下游位置设有排气口长度L 从熔融捏合型挤出机螺杆的最上游部分和L / D为4至18(其中D表示螺杆直径,D和L为相同的刻度单位),同时从所述排气口连续吸入 减压低于660 mmHg。 本发明提供了一种在挤出机中几乎没有树脂降解的方法,即使在相当长的时间内进行加工时,也产生含有少量变色和降解材料的挤压制品。
