摘　　要：采用自制甲基丙烯酸缩水甘油酯接枝高密度聚乙烯 (HDPE g GMA)作为增容剂来增容尼龙 6 /超高分子量聚乙烯 (PA6 /UHMWPE)共混物。通过Molau试验、红外光谱分析、扫描电子显微镜观察和物理力学性能测试 ,研究了HDPE g GMA在熔融共混过程中对PA6 /UHMWPE共混物的增容作用。结果表明 ,HDPE g GMA与PA6发生化学反应所生成的接枝聚合物对PA6 /UHMWPE共混物有较好的增容作用 ;PA6 /UHMWPE共混物的界面形态和力学性能均有较大改善 。The self-made HDPE-g-GMA as a compatilizer to PA6/UHMWPE blends was studied through Molau experiment,IR analysis, SEM observation, and physical and mechanical property test. The results showed that the grafted copolymer, which was produced by HDPE-g-GMA and PA6 being in chemical reaction during melt blending had a good compatibilization on PA6/UHMWPE blends. Interfacial morphology and mechanical property of PA6/UHMWPE blends improved obviously, meanwhile water absorption decreased.
