“…Recently, some interesting studies have been published, for example [12], in which all kinetic parameters are determined from one curve, even for a multi-stage process. On the other hand, there are no papers where the kinetic parameters derived from the dynamic DSC data for the curing of thermosetting polymers are then used to predict the course of the reaction in the isothermal mode.…”

To predict the isothermal course of a reaction from the dynamic DSC curves, the application of isothermal DSC curve transformation has been proposed. To perform such a transformation, it is sufficient only to determine the effective activation energy. To transform integral dynamic curves, a(T)), into isothermal ones, a(t), a better equation has been derived and its validity has been demonstrated on the example of two typical thermosetting ~]~tems. In addition, it hasd~een shown that the transformation of differential curves, (T), into isothermal ones -~-(a), readily allows determination of the kinetic function and rate constants. The procedure used to obtain information on the curing kinetics for thermosetting resins is characterized by simplicity and reliability and can work at E = E(a).
