| Abstract: | The alkylate modification of pullulan which was produced by Aureobacidium pullulans was focused.The alkylpullulans were characterized by SEM,FTIR spectrum,elemental analysis and thermogravimetric analysis.The results showed that the alkylpullulans took the structure of drape with holes in them and improved thermal stability.In addition,the alkylpullulans were water resistant and had good so-lubility in general organic solvents.Therefore,these alkylpullulans would be got a large field of application. |
