摘　　要：采用RH2000型毛细管流变仪对熔融共混制备的聚对苯二甲酸乙二酯(PET)/聚对苯二甲酸丙二酯(PTT)与纳米蒙脱土(MMT)复合物的流变性能进行了研究。结果表明:PET/PTT共混熔体及PET/PTT/MMT复合物熔体均为假塑性流体;复合物熔体的零切黏度(η)0小于PET/PTT共混熔体的η0,MMT的加入起到增塑剂作用;复合物熔体的黏流活化能高于PET/PTT熔体的黏流活化能,说明对PET/PTT/MMT复合物熔体而言,更适合使用调节温度的方法来控制其流动性。The rheological properties of polyethylene terephthalate(PET)/polytrimethylene terephthate(PTT)/ montmorillonite(MMT) composites prepared by melt blending were studied by RH2000 capillary rheometer.The results showed that PET/PTT blend and PET/PTT/MMT composite melts were all pseudo-plastic fluids.The zero-shear viscosity(η0) of the composite melts was lower than that of PET/PTT melt,and MMT acted as plasticizer obviously.The viscous flow activation energy of the composite melts was higher than that of PET/PTT melt,and it is more proper for the PET/PTT/MMT composite melts to control their flow properties by regulating temperature.
