The response of a chemical reaction to temperature modulation has been examined experimentally in an epoxy thermosetting system.
The kinetic response appears in the imaginary part of the complex heat capacity determined by TMDSC. From the imaginary part
and the ‘non-reversing’ heat flow of reaction, the activation energy has been determined. The value of the activation energy
obtained is in good agreement with the value determined from Kissinger's plot utilizing the peak temperatures of the exothermic
reaction with different heating rates.
