| Abstract: | In order to prepare low molecule weight chitosans(oligomers,) the process of chitosan(oxide) degradation by hydrogen peroxide in acetic acid homogeneous phase was investigated.The(molecular) weight and the distribution of chitosan in oxidative degradation process with hydrogen peroxide as oxidant was tracked by GPC.Conditions for preparing different molecular weight(chitosans) in the laboratory was optimized. |
