Modulated differential scanning calorimetry .3. Applications to measurements of the glass transition temperature and increment of heat capacity

Modulated-temperature differential scanning calorimetry was used to measure the glass transition temperature, T-g, the heat capacity relaxation in the glassy state and the increment of heat capacity, Delta C-p, in the glass transition region for several polymers. The differential of heat capacity with respect to temperature was used to analyse T-g and Delta C-p simply and accurately. These measurements are not affected by complex thermal histories.
