STUDY ON THE PROPERTIES OF CURED COMPOUND IN CYANATE ESTER/EPOXY CO-CURING SYSTEM

The influence of composition on the curing kinetic parameter, electrical, mechanical, thermal properties and the glass transition temperature ( T g) of epoxy and cyanate ester co curing system catalyzed by transition metal acetylacetone(M T(atat) n ) was studied by means of DSC,dielectric and dynamic mechanical methods in this paper. The results showed that the reactive activation energy ( E a) 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 ( T g) 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 dielectrical value as well.
