Abstract

A comparison of the values of the glass transition temperature (T_g) measured on cooling and the limiting fictive temperature (T_f^′) measured on heating as a function of cooling rate is performed for a polystyrene sample using both capillary dilatometry and differential scanning calorimetry (DSC). The results from both techniques indicate that T_f^′ is systematically lower than T_g presumably due to the breadth of the relaxation on cooling. The Tool-Narayanaswamy-Moynihan (TNM) model is used to fit the experimental data from dilatometry and DSC in order to ascertain the origins of the higher value of T_g compared to T_f^′.
