Kissinger equation versus glass transition phenomenology
Original language description
The applicability of the Kissinger equation for the evaluation of apparent activation energy corresponding to glass transition kinetics is examined. Theoretically simulated data based on the generally accepted Tool-Narayanaswamy-Moynihan model were usedto represent relevant cases of structural relaxation behavior. The values of the apparent activation energy determined by the Kissinger equation were, despite the linearity of the dependencies, in major disagreement with the original values of a dagger h(*) used for the simulation of the source data. Furthermore, a large dependence of the a dagger h (Kis) (*) evaluation (performed using the Kissinger equation) on the thermal history of the glass was found. The latter represents an unacceptable systematic error in the methodology, implying the incorrectness of the Kissinger equation usage for the evaluation of "glass transition activation energy". This study addresses the currently widespread (incorrect) usage of the Kissinger equation
