Abstract Polycyanurate from dicyanate of bisphenol A was modified with epoxy‐ and phenol‐terminated butadiene‐acrylonitrile rubbers. Rubber‐resincopolymerisation was followed by multiple‐detection gel‐permeation chromatography (GPC). It was found that both the epoxy‐terminated and phenol‐terminated rubbers react with the cyanate and thus are covalently bound with the polycyanurate network. The influence of rubber content, acrylonitrile content and type of end group on phase structure was investigated using dynamic mechanical analysis. Fracture toughness was measured for these modifications.
