Abstract: The influence of composition on the curing kinetic parameter, electrical, mechanical, thermal properties and the glass transition temperature (Tg) of epoxy and cyanate ester co-curing system catalyzed by transition metal acetylacetone (MT(atat)n) was studied by means of DSC, dielectric and dynamic mechanical methods in this paper. The results showed that the reactive activation energy (Ea) and frequency factor (A) of the co-curing is found to increase with enhanced concentrations of cyanate of the co-curing system. The glass transition temperature (Tg) and thermal stability of the cyanate and epoxy cured system is found to increase with enhanced concentrations of cyanate in the same cured condition; addition of the cyanate will decrease the loss factor, and dielectric value as well.
