摘　　要：选用丙烯酸 (AA)和马来酸酐 (MAH)等为接枝改性单体 ,以DCP(过氧化二异丙苯 )、DTBP(二叔丁基过氧化物 )为引发剂 ,研究了不同工艺条件下聚烯烃树脂接枝改性后与极性材料 (如金属铝箔、尼龙等 )的粘结性能以及加入其他树脂稀释后对其性能的影响。研究结果表明 ,对不同类型的聚烯烃树脂 ,选用合适的接枝改性单体、引发剂和工艺条件 ,可以制备出与极性材料粘结性能良好的改性树脂 ;通过适当的稀释 ,在提高 (对PP类 )或不明显降低 (对PE类 )粘结性能的情况下 ,可以匀化改性树脂 ,调整改性树脂的流动性能。此类改性树脂可用作挤出涂覆或共挤出复合的粘结剂、聚烯烃与极性聚合物合金的相容剂或聚烯烃与无机填料共混物的分散剂。With AA and MAH as grafting monomer, DCP and DTBP as initiator,the adhension properties of polyolefins grafted in different processing conditions with polar material such as aluminum foil and nylon ect. were studied,as well as the influences of adding other resins on the adhension properties. The results showed that modified resins had good adhension properties with suitable grafting monomers, initiators and processing conditions. Adding suitable resins could even up modified resins and adjust their flowability. The modified resins could be used as binding agent of extrusion coating and coextrusion composite,compatibilizer of polyolefin and polar polymer alloy, dispersant of filled polymer.
