| 摘 要： | 本文通过Ｍｏｌａｕ实验，二甲苯萃取抽出物的ＩＲ分析，ＤＳＣ，ＳＥＭ测定了尼龙－６／ＰＰ－ｇ－ＭＡＨ的结构，发现尼龙－６与ＰＰ－ｇ－ＭＡＨ的酸酐或羧酸发生了化学反应，生成的接枝共聚物起到了共混体系增容剂的作用，改善了共混物的微观结构形态。流变学测定表明，体系假塑性增加，熔体粘度上升，共混物的成型加工性能较之纯尼龙有所改善。

| Abstract: | Utilizing Molau tests, IR analysis of the xylene extract fractions of the blends,DSC,SEM and capillary rheometer, an experimental study was conducted to investigate the structure and rheological behavior of a blend system consisting of nylon-6 and a maleic anhydride grafting PP. It was found that the graft copolymer reaulted from the reactions between nylon-6 and carboxylated PP during melt blending act as a compatibilizer, which substancially improves micro-structure morphology of blend.The theological measurements showed that compared to pure nylon, the nylon/PP-g-MAH blending system would posses higher pseudo-plasticity and melt viscosity, and better processability. |
