Abstract

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, δCp, in the glass transition region for several polymers. The differential of heat capacity with respect to temperature was used to analyseT g and δCp simply and accurately. These measurements are not affected by complex thermal histories.
