摘　　要：采用平板动态流变仪研究了聚碳酸酯/尼龙6(PC/PA6)共混体系在设定温度下的动态流变性能,并探讨了增容剂用量、剪切频率等因素对高聚物动态复合黏度、动态储能模量及损耗因子等动态流变参数的影响。结果表明,PA6的加入明显改善了PC的加工流动性,3种增容剂的加入增强了分子间作用力和分子链之间的缠结,提高了界面黏合力。Dynamic rheological properties of PC/PA6 blends were studied by plate dynamic rheometer at certain temperatures, and the effects of the use amount of compatibilizer and shear rate on the rheological parameters, such as dynamic complex viscosity, dynamic storage modulus and loss factor were also investigated. The results indicate that： the addition of PA improves the processing rheological properties of PC obviously, the addition of 3 kinds of compatibilizers improves the interaction between PC and PA6, resulting in the enhancement of the interfacial adhesion.
