Abstract:

There are three distinct types of epoxides in the SP-250 system. The epoxides were individually mixed with Monuron. Also, three-component mixtures, epoxide DicyMonuron, were prepared with dicyandiamide. The mixtures were cured by differential scanning calorimetry. It was found that the isothermal heat of reactions of the two- and three-component systems were in reasonable agreement with the respective dynamic recations, consequently, the extent of isothermal cures could be determined from the two heating modes. The synergistic effect of dicyandiamide and monuron, on the curing process, was simulated by the isothermal reaction of two mixtures. A type of reaction Kinetics having the dimensions of temperature per time was evaluated in this report.
