摘　　要：粒度分析结果表明,CaCO_3在聚苯乙烯中的分散符合Rosin-Rammler分布。实验表明,随CaCO_3中偶联剂用量、聚苯乙烯中CaCO_3含量的增加以及体系在混炼过程中所受剪切程度的降低,体系中CaCO_3的特征粒径逐渐增大。但上述三因素对CaCO_3的分散指数影响不大。The particle size analysis indicated that the dispersion of nano - CaCO3 in polystyrene (PS) conformed to Rosin - Rammler distribution. Characteristic diameter (De) of the nano - CaCO3 in the system gradually augmented either with increasing the dosages of coupling agent in CaCO3 and the content of the nano - CaCO3 in PS or with reducing the shear rate of the system during the mixing process. However, the three factors mentioned above exerted a little influence on the dispersion index of the nano - CaCO3 in PS.
