摘　　要：采用双螺杆挤出机,通过熔融共混法分别制备了PA6/EVA-g-MAH、PA6/POE-g-MAH和PA6/EPDM-g-MAH共混合金,研究了各种接枝弹性体用量对合金形态结构及性能的影响。结果表明:合金的拉伸强度和熔体指数均随弹性体用量的增加而减小。3种接枝弹性体的加入对PA6的冲击韧性都有一定的改善,POE-g-MAH和EPDM-g-MAH的增韧效果尤为明显。Using twin-screw extruder, PA6/EVA-g-MAH, PA6/POE-g-MAH and PA6/EPDM- g-MAH alloys were prepared respectively by melt-compounding method, and the effects of the content of various grafted elastomers on morphology and performances of the alloys were researched. The results showed that tensile strength and melt flow rate decreased with the increase of the content of elastomers. The addition of all these there kinds of grafted elastomers had certain improvement on the impact toughness of PA6,especially POE-g-MAH and EPDM-g-MAH.
