摘　　要：讨论了甲基丙烯酸缩水甘油酯(GMA)接枝聚丙烯(PP)的反应以及PP接枝GMA共聚物(PP-g-GMA)在PP/聚酰胺6(PA6)合金中的应用。结果表明,以过氧化二异丙苯(DCP)为接枝反应最佳引发剂,最佳工艺条件为:GMA:DCP=10～12:1,GMA的用量为6％,停留时间120～180 s。同时,PP-g-GMA能够提高PP和PA6的相容性,从而改善合金的拉伸、韧性、亲水性和热性能。This paper discussed the reaction for making glycidyl methacrylate (GMA) grafted polypropylene (PP) and the application of PP - g - GMA in PP/polyamide 6(PA6)alloys. The results showed that dicarbonate peroxide (DCP) was the best initiator for the graft reaction. The optimum conditions for the grafting reaction were as follows: the ratio of GMA to DCP being 10 - 12 : 1, the amount of GMA 6%, and the residence time 120 - 180 seconds. In addition, PP - g - GMA could increase the compatibility between PP and PA6, and consequently improved the tensile strength, toughness, water absorption and heat resistance of the alloy.
