摘　　要：以硝酸铈铵为引发剂，在微波条件下，对壳聚糖与二甲基二烯丙基氯化铵接枝反应的因素进行进行分析。结果表明最佳条件为：单体与壳聚糖的质量比为3：1，温度为40℃，引发剂浓度为0．5mmol/L，时间是15min，微波功率为300W。通过红外光谱图对共聚物进行了表征；共聚物在固色性能上比固色剂有了较大的提高。With cerium ammonium nitrate as the initiator, chitosan-DMDAAC graft copolymer was synthesized under microwave radiation. Factors that affect graft copelymerization were discussed. The optimum conditions were confirmed： the monomer to chitosan mass ratio 3：1, the reaction temperature 40℃, the initiator concentration 0.5mmol/L, reaction time 15min, microwave power 400W. the structure a of the products were characterized by using infrared spectroscope （FFI）. the fixing effection of chitosan polymer has greatly improved than fixing agent.
