Abstract :
Differential Scanning Calorimetry (DSC), ThermoMechanical Analysis (TMA) and Thermally Stimulated Current (TSC) spectroscopy have been applied to the study of the glass transition of a polyurethane elastomer. By DSC, we observe the step associated with the glass transition of the polymer. TMA shows a step in the linear thermal expansion coefficient and the TSC spectrum exhibits a relaxation mode with two components in the temperature range of the glass transition
