摘　　要：本文研究了不同的分散剂对PP/纳米CaCO3 体系的分散效果 ,以及加工工艺条件对该体系的影响。结果表明 :超分散剂CH -1A对纳米CaCO3 有显著的分散作用 ,使体系的冲击强度有了大幅度提高。在使PP完全塑化的前提下 ,超分散剂CH -1A使纳米CaCO3 在PP中随转速的提高其分散效果也提高 。s Dispering effects of three different kinds of dispersants on PP/nano CaCO 3 system and influences of processing parameters on it were studied,the results showed that hyper dispersant CH 1A had the most excellent dispering effect on nonao calcium carbonate in PP and made the impact strength of the system markedly improved.The dispering effect of hyper dispersant CH 1A became better with the increase of rolling speed if PP was wholly plasticized and made the system have a better processing properties.
