摘　　要：超支化聚合物的合成与应用是目前研究的热点。应用自制的超支化分散剂(Hyperbranched dispersant,HPD)与不同的表面活性剂复配,制备水性颜料分散体系,研究其他表面活性剂种类、超支化分散剂与表面活性剂比例等条件对颜料分散体系的粒径及其分布、离心、稳定性等性能的影响。实验结果表明:超支化分散剂与非离子表面活性剂复配比为7∶3、与阴离子表面活性剂复配比为6∶4时,体系的分散性和稳定性较好。超支化分散剂与阴离子分散剂复配效果较好。The study on synthesis and application of Hyperbranched Polymer is popular. Remixing Hyperbranched dispersant （Hyper- branched dispersant,HPD）with other surfactant to prepare water-based pigment dispersion. This paper expounds the effect of several conditions to the pigment size and the systemic stability, such as types of surfactants, the ratio of HPD and surfactants. While theratio of hyperbranched dispersant to non-ionic surfactant is 7：3 ,and the ratio of it to is anionic surfactant is 6：4 ,the system has good dispersibility and stability. The effect of remixing hyperbranched dispersants with anionic dispersant turns better.
