Abstract
Polytriazines exhibiting improved toughness without sacrificing heat resistance are prepared by curing a cyanate ester resin having dispersed therein resin-insoluble rubber particles grafted with a resin-soluble polymer. The resin-soluble polymer stabilizes the rubber particles and maintains the particles in an essentially discrete, nonagglomerated form.
