| 摘 要： | 交联壳取聚糖／Ｃｕ＾２＋／亚硫酸钠体系能够在室温下于水溶液中引发甲基丙烯酸甲酯聚合。单位时间内单体的转化离随反应温度，膜内交联剂的含量，亚硫酸钠浓度的增加而增加。产物的分子量随温度的升高而降低，反应机理符合自由基聚合机理。

| Abstract: | The cross-linked chitosan (cr-CS)/Cu2+/Na2SO3 system can initiate the polymerization of methyl methacrylate in aqueous solution at room temperature. The conversion of monomer in unit time increased with increasing the reaction temperature and the content of cross-linking agent in the cr-CS membrane as well as the concentration of Na2SO3. The molecular weight of PMMA decreased with increasing the reaction temperature. The polymerization is proceeded by free radical mechanism. |
