【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。更多还原

【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.更多还原
