交联壳聚糖／Cu2+／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率随反应温度、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．
The cross-linked chitosan / Cu2 + / sodium sulfite system is capable of initiating the polymerisation of methyl methacrylate in aqueous solution at room temperature. The conversion rate of monomer per unit time with the reaction temperature, the content of cross-linking agent in the membrane, sodium sulfite concentration increases. The molecular weight of the product decreases with increasing temperature. The reaction mechanism conforms to the free radical polymerization mechanism.
