通过熔融挤出法制备甲基丙烯酸缩水甘油酯(GMA)接枝聚烯烃弹性体(POE-g-GMA)后，又以此作为增韧剂，通过双螺杆挤出机制备了POE-g-GMA增韧PC/ABS合金。通过改变物料配比，确定引发剂过氧化二异丙苯(DCP)，GMA与POE的最佳比例为DCP/GMA/POE=0.75/4.25/100。PC/ABS最优比例为PC∶ABS=7∶3。以此为基材，探讨了POE-g-GMA对该合金体系力学性能的影响。结果表明，POE-g-GMA在PC/ABS合金基体中均匀、稳定分散，可以实现对合金体系的增韧，当配比为POE-g-GMA∶PC/ABS=3∶100时，综合性能达到最优。

Glycidyl methacrylate(GMA) grafting polyolefin elastomer(POE-g-GMA) was prepared by melting process. As a flexibilizer,POE-g-GMA was used to toughen PC/ABS alloy by extrusion processing. By changing the ratio of raw materials,the optimal proportion of DCP,GMA and POE is 0.75/4.25/100. The optimal proportion of PC/ABS is 7∶3. The influence of POE-g-GMA on the mechanical performance of PC/ABS alloy was studied. The results show that POE-g-GMA is dispersed uniformly in PC/ABS alloy matrix,and could be effective in toughening PC/ABS alloy. When the ratio of POE-g-GMA∶PC/ABS is 3∶100, PC/ABS alloy has the best comprehensive properties.
