摘　　要：采用PP熔融接枝MAH和不饱和羧酸混合单体通过反应挤出增容PP/PA6共混物 ,研究了增容共混物两相间的界面相互作用。通过Molau实验、抽提实验、IR测试等证明 :接枝物增容的PP/PA6共混物 ,由于在熔融挤出共混过程中 ,接枝物的反应基团和PA6的端氨基发生化学反应就地生成了PP -g -PA6 。The interfacial interaction of compatibilized PP/PA6 blend prepared by melt grafting of PP with MAH and other unsaturated acid has been studied. The results of Molau test, extraction and IR measurement showed that there were strong interfacial interaction between two phases of the compatibilized PP/PA6 blend, due to the reaction between the reactive groups of PP to form PP-g-PA6 on the interface during melt extrusion of grafted PP and PA6.
