Abstract
In this paper, the results showed that the addition of an appropriate amount of reactive rubbers ((ie: carboxyl randomized butadiene-acrylonitrile rubber (CRBN) and hydroxyl terminated butadiene-acrylonitrile rubber (HTBN)) to epoxy resin/cyanate ester resin (EP/CE) (70/30) improved both the mechanical properties and thermal stability of the resulting blends. CRBN and HTBN have different reactive activity and dispersion state in EP/CE/rubbers. No drop in the thermal stability of the EP/CE network with addition of these two rubber component is related to the low rubber concentrate and the reactions between the rubbers and EP or CE.
