| Abstract: | A narrow distribution low molecular weight chitosan(LMWCTS) was prepared by the oxide(degradation) system adjusted with trace amount of zinc sulfate.Fluorescence probe was used to investigate the polarity of micro-area of this degradation system,IR and GPC were utilized for measuring the physic-(chemical) properties of these LMWCTS samples.The system with 3.8 mmol ZnSO_(4) had a narrow distribution of LMWCTS(M_(w)=973,d=1.1) and the yield of LMWCTS was 85%.Those primary structure units of the chitosan have not been altered after degradation. |

| Keywords: | low molecular weight chitosan oxide degradation polarity of micro-area |
