| 摘 要： | 以硝酸铈铵为引发剂,利用二甲基二烯丙基氯化铵（DMDAAC）在羧甲基壳聚糖骨架上的接枝反应,制备了羧甲基二甲基二烯丙基氯化铵壳聚糖（CMCTS-DMDAAC）.通过三因素三水平正交实验得出羧甲基壳聚糖与DMDAAC反应的优化实验条件为：反应温度为90℃,反应pH为7.0,反应时间为2 h,引发剂用量为占羧甲基壳聚糖质量的1.5%,单体用量为羧甲基壳聚糖质量的1.5倍.反应产物的结构通过红外光谱、紫外光谱、热重/差热分析、X-衍射及扫描电镜进行了表征.

| Abstract: | Carboxymethyl chitosan-dimethyl-diallyl-ammonium chloride（CMCTS-DMDAAC） was prepared via graft reaction of dimethyl-diallyl-ammonium chloride onto the chain of carboxymethyl with ammonium cerium nitrate as initiator.The reactive conditions between the carbox-ymethyl chitosan and quaternizational reagent DMDAAC was optimized by three factors and three levels orthogonal experiment as follows： the reaction temperature is 90 ℃;reaction pH value is 7.0;reaction time is 2 h;the initiator amount was 1.5 % of the chitosan quantity;monomer amount was 1.5 times as chitosan quantity.The product structure was characterized by using IR,UV,X-ray diffraction,TG/DTA and SEM. |
