With HIPS as matrix resin,the toughening modification of impact modifier SBS on HIPS was stud- ied by using twin-screw extruder,and the effect of the technical conditions on property of prepared toughened HIPS was also studied.

• 以高抗冲聚苯乙烯(HIPS)为基体树脂,采用双螺杆挤出机研究了抗冲击改性剂SBS对HIPS的增韧效果,探讨了制备工艺条件对超韧HIPS材料性能的影响。
