Abstract: A new temperature-modulated differential scanning calorimetry (TMDSC) technique is introduced. The technique is based on stochastic temperature modulation and has been developed as a consequence of a generalized theory of a temperature-modulated DSC. The quasi-static heat capacity and the frequency-dependent complex heat capacity can be determined over a wide frequency range in one single measurement without further calibration. Furthermore, the reversing and non-reversing heat flows are determined directly from the measured data. Examples show the frequency dependence of the glass transition, the isothermal curing of thermosets and a solid–solid transition.
