Abstract
A new evaluation method for determining the kinetic parameters of a ch emical reaction from DSC measurements is presented. This method evalua tes a series of thermograms at different heating rates. The activation energy, the frequency factor and a general description of the concent ration dependence of the reaction rate are obtained. Theorical DSC cur ves are also evaluated and the results obtained are compared with the prescribed parameters.
