摘　　要：在转矩流变仪中,分别用α-甲基苯乙烯(AMS)和癸烯做共单体,将马来酸酐(MAH)熔融接枝在全同聚丁烯-1(iPB-1)上。采用红外光谱仪(FTIR)、熔体流动速率仪等对接枝样品进行测试,探索了MAH、共单体AMS和癸烯、引发剂含量对接枝物的MAH接枝率和加工性能的影响。结果表明:AMS与癸烯可显著提高iPB-1的MAH接枝率,同时也会引起交联反应;AMS对MAH在iPB-1上接枝率的影响比癸烯大;与癸烯相比,交联AMS共单体的接枝反应更明显。iPB-g-MAH was obtained by melt-grafting of MAH onto iPB-1 with comonomers（AMS or decene） mixing in the torque rheometer. The influence of content of MAH, AMS/decene and DTBP on grafting degree of MAH and processing properties of grafting products were studied. The results show that AMS and decene can significantly increase the grafting degree of MAH on iPt3-1, and can also cause crosslinking reaction. The influence of AMS on grafting degree of MAH is greater than that of decene. Compared with decene, crosslinking reaction of AMS co-monomer is more obvious.
