摘　　要：以工业化的聚苯乙烯中空微球为模板,利用种子乳液法合成了粒径均一的功能化中空聚苯乙烯/聚4-乙烯基吡啶(PS/P4VP)微球,改变制备条件可以控制功能基团4-乙烯基吡啶(4-VP)在聚苯乙烯微球表面的分布。合成的微球在水和有机溶剂如二氯甲烷、乙醇、乙腈等中有良好的分散性,并能促进油水体系混溶。The functional polystyrene/poly 4-vinylpyridine （PS/P4VP） microspheres with narrow particle size distribution were prepared by seeded emulsion polymerization using commercial polystyrene hollow spheres as template. The distribution of 4-VP grafted on the surface of the hollow polystyrene microspheres could be controlled by changing parameters of reaction. The PS/P4VP microspheres could be dispersed into both water and organic solvents such as dichloromethane, ethanol and acetonitrile. They could also increase the miscibility of water- dichloromethane system.
