摘　　要：分散体系中不同的聚合过程能够制备出具有不同功能特性的纳米凝胶,这些聚合物可广泛应用在生物医学、靶向药物输送和其他领域。综述了反应溶剂对聚合过程的调控,重点介绍了乳液聚合和分散聚合,通过调节溶剂组成引发乳液聚合与分散聚合的转化。探讨了溶剂极性、溶解度参数和聚合反应的临界链长等参数对聚合方式的影响。Different polymerization processes in the dispersion system can prepare nanogels with different functional properties.These polymers can be widely used in biomedicine,targeted drug delivery and other fields.The control of the reaction solvent on the polymerization process is reviewed,and the focus is on e-mulsion polymerization and dispersion polymerization.The conversion of emulsion polymerization and dis-persion polymerization is caused by adjusting the solvent.The effects of solvent polarity,solubility parame-ters,and critical chain length of the polymerization reaction on the polymerization method are discussed.
