Study on the properties of cured compound in cyanate/epoxy co-curing system

摘要

The influence of composition on the curing kinetic parameter, electrical, mechanical, thermal properties and the glass transition temperature (T/sub g/) of cured compounds of the epoxy and cyanate co-curing system catalyzed by transition metal acetylacetone (M/sub /spl tau//(acac)/sub 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 /spl delta/ /spl epsi//sub r/ of the co-cured compound would gradually decrease in the same cured condition.
