| 摘 要： | 本文利用自行设计的一种新型毛细管动态流变仪，研究了挤出过程中振择ＰＰ／ＣａＣＯ３体系混合特性的影响。当ＰＰ／ＣａＣＯ３填充体系在一较佳振荡条件下挤出时，振荡 非常有利于ＣａＣＯ３在ＰＰ熔体中的分散。实验研究表明，有效的振荡作用能促进低分子填料在聚合物熔体中的分散，从而使填充聚合物体系具有良好的混合特性。

| Abstract: | The effect of oscillations during extrusion on the mixing characteristic of PP/CaCO 3 system is carried on with a new self_designed capillary dynamic rheometer. When PP/CaCO 3 system is extruded under a better oscillation extrusion, the oscillation is greatly beneficial to the dispersion of CaCO 3 in PP. The experimental study shows that an effective oscillation can promote the dispersion of a low molecular filler in polymer melt and makes filled polymer system get good mixing characteristics. |
