摘　　要：本文采用硝酸铈铵为引发剂,合成了壳聚糖与马来酸酐的接枝共聚物。固定引发剂浓度1.5mmol/L,通过正交实验对合成工艺条件进行了优化,最佳合成工艺条件为反应温度90℃,反应时间3h,壳聚糖与马来酸酐摩尔比为1∶2,pH=6。并对接枝共聚物进行了红外光谱与紫外光谱表征。The graft - copolymer was synthesized by grafting maleic anhydride onto chitosan with cerium ammonium nitrate as initiator. The fixed concentration of initiator was 1.5mmol/L, the optimum reaction conditions for the synthesis of graft - copolymer were determined by means of orthogonal experimental design. The conditions were as follows：the reaction temperature and time were 90℃ and 3 h, the monomers mole ratio of chitosan and maleic anhydride was 1：2, pH = 6, and the polymer was verified by IR and UV spectrum.
