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 compound of epoxy and cyanate co-curing system catalyzed by transition metal acetylacetone (M{sub}t(acac){sub}n) was studied by means of DSC dielectric and dynamic mechanical methods in this paper. The results found the reactive activation energy (Ea) and frequency factor (A) of co-curing system gradually increase with enhanced concentrations of cyanate and tanδ, ε{sub}r of co-cured compound would gradually decrease in the same cured condition.
