Acrylated cyclophosphazene was used as a flame retardant to blend with commercial UV-curable epoxy acrylate EB600. The kinetics of thermal degradation of the UV-cured product was studied by thermogravimetric analysis at different heating rates in comparison with that to use cyclophosphazene powder in place of the acrylated one. The activation energies and correlation coefficients were calculated by Kissinger, Flynn-Wall-Ozawa and Friedman methods. It has been shown that the addition of cyclophosphazene increased the activation energies of blend systems at high temperature, improved the thermal stability and made the thermal degradation more difficult. Moreover, the acrylated cyclophosphazene film has higher activa-tion energy than that containing cyclophosphazene powder.
Key words: cyclophosphazene, epoxy acrylate, thermogravimetric analysis, kinetics of thermal degradation
