摘　　要： 以硝酸铈铵为引发剂引发壳聚糖 (Cs)与甲基丙烯酸 (MAA)接枝共聚。用元素分析、红外光谱、X -射线粉末衍射对接枝共聚物进行分析 ,并研究了接枝共聚物膜材料的力学性能和溶解性能。结果表明 ,由于接枝聚合 ,使Cs大分子原来的结晶结构受到破坏 ,韧性得到了一定的改善 ,经 2 %的氢氧化钠溶液处理过的Cs- g -MAA接枝共聚物膜 。 The grafting co-polymerization of chitosan (Cs) with methyl acrylic acid (MAA) was carried out using (NH 4) 2Ce(NO 3) 6 as initiator. Results of elemental analysis, FT-IR and X-ray diffraction showed that the crystal structure of Cs was destroyed due to the grafting co-polymerization. For the same reason, the toughness of Cs was improved to a certain extent. Dissolubility testing of the membrane of Cs and Cs-g-MAA (containing PMAA) indicated that after treated with a solution of 2 % NaOH, the latter was offered with a good solvent resistance, in comparison with that of pure Cs.
