Description

Based on the expression of the apparent heat capacity with the contribution of transition kinetics, the applicability of temperature modulated DSC (TMDSC) has been discussed. In order to examine the kinetic response in the apparent heat capacity, the details of the frequency dependence has been examined. On crystallization, the kinetic response appears only in the imaginary part, and the temperature dependence of linear growth rate is obtainable from TMDSC data alone. In the melting region, the apparent heat capacity shows strong frequency dispersion. From the heating rate dependence of the characteristic time, one can evaluate the superheating dependence of melting rate. TMDSC can also differentiate re-crystallization and re-organization from melting since the temperature dependence of those processes is expected to be weak enough compared to melting.
