摘　　要：通过马来酸酐酰化改性制取水溶性壳聚糖,利用沉淀缩聚方法将尼龙接枝于该水溶性壳聚糖上。通过改变原料的配比得到不同接枝率和溶解性的产物,较合适的原料投料比为n(马来酰化壳聚糖(MACS))∶n(己二胺)∶n(丁二酰氯)=1∶10∶7.5。采用FTIR和1H NMR测试技术表征了壳聚糖接枝尼龙的结构。初步研究表明,壳聚糖接枝尼龙在尼龙和壳聚糖的共混中能起到一定的增容作用。Water-soluble chitosan was prepared by modification of chitosan with maleic anhydride, and then nylon 64 was grafted onto it by condensation polymerization. Products of different graft percentage and solubility were obtained by altering reagent feed ratio, and the optimum reagent feed ratio was determined to be n（MACS）：n（hexamethylene diamine）： n （butanedioic acid chloride） = 1：10： 7. 5. The structure of the chitosan-graft-nylon was characterized by FTIR and ^1H NMR. The preliminary results show that chitosan-graftnylon can be used as a compatibilizer in the blends of chitosan and PA64.
