摘要

Abstract

Graft copolymer of chitosan was prepared using acrylamide. The grafting reaction was initiated by ammonium persulfate and sodium sulfite. The graft copolymer was characterized by FT-IR,X-ray and SEM techniques. The grafting percentage was also analysed. The grafting percentage showed maxima with 68.5% D.D.(degree of deacetylation) of chitosan under appropriate condition, around 250% grafting percentage was achieved. The best synthesis condition is m(chitosan):m(AM)=1:5; redox indicator 0.3%-0.4% mass fraction of solution; reaction temperature 55-60 ℃; reaction time 2.5-3.0 h.
