| 摘 要： | 采用 CFT-5 0 0型毛细管流变仪研究了含 COP(含 -SO3N a的共聚酯 ) / PP共混物的流变性能。结果表明 :COP/ PP共混物为假塑性流动 ,其偏离牛顿流动行为的程度与共混物构成有关。在 2 65℃和 2 80℃时 ,COP/ PP共混物的表观粘度随 COP含量的增加而减小 ;COP含量增加 ,共混物的粘温依赖性增大。

| Abstract: | With CFT\|500 capillary rheometer, the rheological properties of copolyester containing -SO 3Na(COP)/PP blend were studied. The experimental results showed that the COP/PP blend is pseudoplastic fluids, and the departure from Newtonian fluids behavior depends on the composition of the COP/PP blend. The apparent viscosity of the COP/PP blend decreases with the increase of COP at 265℃ and 280℃. The temperature dependence of viscosity increases with increasing COP content. |
