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.
