“…Any study of reaction kinetics requires the following fundamental data: reaction rate and degree of conversion. The quantitative DSC technique is commonly used for monitoring the process and for evaluating not only the heat of reaction, but also the reaction kinetics [22,23]. In this technique it is common to assume that the rate of exchanged heat evolution is strictly proportional to the rate of the global chemical reaction(s) at any time as follows [24,25]:…”

The curing of an unsaturated polyester resin catalyzed with methylethylketone peroxide and cobalt octoate as promoter is studied by DSC at different heating rates. A high promoter/peroxide ratio is used. The DSC curves show two exothermic peaks. It has been assumed that they represent two independent cure reactions. A set of kinetic parameters for each DSC peak has been obtained. They describe the overall cure process using an empirical kinetic model. Nth order and autocatalytic kinetic functions have been employed. A computer program was developed to calculate the degrees of conversion associated with each peak, and to evaluate the kinetic parameters. The calculation algorithm uses the Runge-Kutta numerical integration and the ' 'downhill simplex method.' ' This methodology permits to find all kinetic parameters simultaneously. DSC experimental data are very well fitted. The simulated first peak occurs always before the second one, and the fraction of reaction heat associated with the first peak over the overall reaction heat decreases with heating rate. Moreover, activation energies are in good agreement with the tabulated values for typical free radical polymerization induced by thermal and redox decomposition of the peroxides. POLYM. ENG.
