Abstract

The influence of the ratio of epoxy (EP) to dicyclopentadiene bisphenol cyanate ester (DCPDCE) on the curing behavior of EP/DCPDCE system was studied using differential scanning calorimetry and Fourier transform infrared spectroscopy. The conversion of —OCN groups and the formation of the reaction products in the different EP/DCPDCE systems and at different curing steps were determined. The results show that the epoxy resin has both a catalytic effect and a dilution effect on the trimerization reaction of —OCN groups. These two effects reach an approximate balance when the content of epoxy resin in the EP/DCPDCE system is 15 wt.%. In addition, the epoxy resin can improve the final conversion of —OCN groups, and the initial amount of epoxy resin has a significant influence on the final structure of the co-polymers.
