| 摘 要： | 聚合填充法制备的UHMWPE/Kaolin复合材料具有特殊的流变行为。一般情况下填料的加入使聚合物熔体粘度,动态模量升高。与此相反,由填充复合法制备的UHWMPE/Kaolin复合材料的表观粘度、复数粘度、动态模量均随Kaolin填充量呈下降趋势,其加工性得到改善。文中对此现象的实验结果进行了报道,并探讨了流变行为与聚合填充法赋予复合材料的独特结构的关系。

| Abstract: | The steady and dynamic rheology behaviors of UHMWPE/Kaolin composites prepared by a polymerization-filling method were investigated with capillary and parallel plate rheometer. The composites showed an unusual rheological behavior.The material could be smoothly extruded through the capillary and the addition of Kaolin particles could decrease the apparent viscosity, dynamic viscosity, complex viscosity and the moduli of the melt. The relationship between rheological behaviors and the unique structure governed by polymerization-filling was further discussed. |
