| 摘 要： | 主要讨论了ＬＤＰＥ、ＰＰ与马来酸酐（ＭＡＨ）在熔融挤出反应中，引发剂ＤＣＰ的用量、ＭＡＨ 的用量以及反应温度、物料的停留时间对接枝物的影响。结果表明：在ＬＤＰＥ接枝过程中，ＤＣＰ用量为０．０８～０．１ 份，ＭＡＨ 用量为４～５ 份，反应温度１６０～１７０℃，螺杆转速为４０～５０ ｒ·ｍ ｉｎ－ １为宜。对ＰＰ接枝过程中ＤＣＰ用量为０．２～０．４ 份，ＭＡＨ用量为５～７ 份，反应温度为１７５～１８０℃，螺杆转速为３０～３５ ｒ·ｍ ｉｎ－ １为佳

| Abstract: | During melt extrusion grafting of maleic anlydride(MAH)onto LDPE and PP,the effects of initiator(DCP) content,monomer(MAH) content,reaction temperature and time were studied. The results showed that DCP content=0.08～0.1,MAH content=4～5,reaction T=160～170℃, screw rotation speed=40～45 r.min -1 were good for LDPE grafting,and that DCP content=0.2～0.4,MAH content=5～7,reaction T=175～180℃,screw rotation speed =30～35 r.min -1 were good for PP grafting. |
