[14-17]), but these forms of equations are not satisfactory due the two-modal dependencies (see Fig. 1) that have been reconstructed from the DSC scanning data. Fig. 1. Kinetics curves for three different heating rates To describe such kinetics dependencies a new kinetic model and empirical dependence for heat capacity have been proposed [18] (1) , (2) where are the kinetic model parameters defined by smoothing the kinetic curve; and are the specific heats of uncured (liquid) and fully polymerized (solid) resin respectively; conversion corresponds to the jump of heat capacity at the phase transition; and the width of the jump in the smoothed Heaviside function for the studied resin have defined by these empirical relationships ; . Equation (2) describes the jump of the heat capacity at the phase transition, and broadening of this jump with increasing heating rate.
