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-graft-nylon can be used as a compatibilizer in the blends of chitosan and PA64.
