Abstract
It is well known that both the glass transition temperature (T g) and the limiting fictive temperature (T f') depend on the cooling rate. However, a comparison of the values of T g and T f' as a function of cooling rate has not previously been performed. In this work we have performed this comparison for a polystyrene sample using both capillary dilatometry and differential scanning calorimetry. The results from both techniques indicate that both T g and T f' have almost the same dependence on the cooling rate. However, T f' is systematically lower than T g presumably due to relaxation that occurs on heating.
