Abstract :
The influence of composition on the curing kinetic parameter, electrical, mechanical, thermal properties and the glass transition temperature (Tg) of cured compounds of the epoxy and cyanate co-curing system catalyzed by transition metal acetylacetone (Mτ(acac)n) was studied by means of DSC, dielectric and dynamic mechanical methods in this paper. The results found that the reactive activation energy (Ea) and frequency factor (A) of the co-curing system gradually increase with enhanced concentrations of cyanate and tan δ εr of the co-cured compound would gradually decrease in the same cured condition
