Abstract
The graft copolymerization of acrylonitrile onto chito sa n was prepared using NaHSO_3-K_2S_2O_8 as initiator. The results showed tha t the optimum process conditions were as follows: =0.011 mol/L, =0.010 mol/L,=0.50 mol/L, chitosan concentration was 1.0 g/100 mL, reaction time 4.5h,temperature 60℃. The grafting(G%) and graft efficiency(E %) were 168.76%,80.63% respectively under the optimum process conditions.
