Abstract
Inulin was employed as a typical hydrophilic polymer, and glass transition temperature (T_g) of various types of inulin was investigated by using differential scanning calorimetry. The T_g of inulin samples decreased with increasing water content and decreasing molecular weight. The effect of water content on the T_g of inulin samples could be described by the Gordon-Taylor equation. Furthermore the effect of molecular weight on the T_g of anhydrous inulin samples could be described by a stretched exponential equation. From these results, the T_g of amorphous inulin can be predicted.
