摘　　要：水溶性单体在盐水介质中的分散聚合是一种新型绿色合成技术。本研究通过丙烯酰胺(AM)和阳离子单体甲基丙烯酰氧乙基三甲基氯化铵(DMC)在无机盐水溶液中的分散共聚合,制备了稳定的P(AM-DMC)水基分散体。采用扫描电镜、激光粒度仪测定了粒子形貌和粒径。研究了稳定剂结构与用量、共聚单体组成、第三单体盐的种类和浓度对水基分散聚合的影响。The dispersion polymerization of water soluble monomers in aqueous solution is a new kind of green synthesis technology. Stable aqueous dispersions of P（AM-co-DMC） by the copolymerization of acrylamide （AM） and cationic monomer （2-methacryloyloxyethyl） trimethyl ammonium chloride（DMC） in inorganic salt solution was prepared. The shapes and sizes of the particles were determined by SEM and laser particle analysis. The effects of factors, such as the structure and amount of dispersants, the composition of monomers, the nature and concentration of inorganic salts, on dispersion polymerization were studied.
