Abstract
Temperature Modulated Differential Scanning Calorimetry (TMDSC) is a
relatively new thermal analysis technique that incorporates not only the ability of
conventional DSC, but also provides significant and distinct advantages over
traditional DSC. We first review the principles of TMDSC and then provide a
number of characterization-type applications to glasses and polymers. The glass
transition temperature Tg measurements by conventional DSC usually involve
heating scans and, consequently, the measured Tg depends sensitively on the
thermal history and aging. We demonstrate that, in contrast to DSC, TMDSC
measurements can conveniently provide a more meaningful and reproducible
characterization of the glass transition properties of glasses and
