聚烯烃接枝马来酸酐作为增容剂的应用

The uses of compatibilizers made from maleic anhydride grafted polyolefins

陈民杰  张军 

摘 要:聚合物共混改性是制备新型高分子材料极为有效的方法,其中的关键是要解决各种聚合物之间一般相容性很差的问题,通常的解决办法是加入合适的增容剂,聚烯烃接枝马来酸酐(PO-g-MAH)是研究的很多的增容剂.制备聚烯烃接枝马来酸酐的方法有熔融法、溶液法、辐射法和固相法,其中最重要的方法是熔融法,笔者主要介绍了聚烯烃接枝马来酸酐作为增容剂在改性聚酰胺(PA6、PA66、PA12、PA1010)、聚酯(PET、PBT)、热塑性聚氨酯(TPU)等聚合物共混物,聚烯烃/无机填料,聚烯烃/有机纤维,复合增强材料,粘结剂等方面的应用,聚烯烃接枝马来酸酐与其它聚合物原位反应生成共聚物,一方面降低了表面张力,使得分散相在基体中分散得更好;另一方面增强了两相的粘合力,从而达到了增容的目的.
