摘　　要：目的研究ＨＤＰＥ／ＨＤＰＥ－ｇ－ＭＡＨ／ＣａＣＯ３共混物的流变性能．方法借助毛细管流变仪，考查了ＣａＣＯ３含量，ＨＤＰＥ－ｇ－ＭＡＨ含量对共混材料流变性能的影响．结果ＣａＣＯ３和ＨＤＰＥ－ｇ－ＭＡＨ的加入使体系的粘度上升，体系的非牛顿性增强．Aim\ To study the rheological property of HDPE/HDPE g MAH/CaCO 3 blends. Methods\ The effect of disperse phase quantity about CaCO 3 and HDPE g MAH on rheological property were discussed by capillary rheometer. Results\ The apparent viscosity was increased by added CaCO 3 and HDPE g MAH. The non newtonian behavior of blends was increased, too. Conclusion\ The results have a guide function for producing technology and mold design.
