FIELD: physics.
SUBSTANCE: present invention relates to curable compositions. Described is curable epoxy resin composition for producing thermosets or cured products containing divinyl aren dioxide, including (a) stoichiometric excess equivalent of at least one divinyl aren dioxide, (b) co-reacting curing agent, which is phenol novolac resin, bisphenol A novolac resins, dicyclopentadiene phenol novolac resins, cresol novolac resins or their combination, and (c) catalyst, which is tertiary amine, imidazoles, quaternary ammonium salt, quaternary phosphonium salt, Lewis acid - Lewis base complexes or mixture thereof, for interaction of excess epoxide, in which said divinyl aren dioxide concentration varies within range of stoichiometric ratio of epoxy groups to number of groups co-reacting curing agent approximately of 1.05-10. Invention also describes method of producing said curable composition and method for production of hardened thermoreactoplast. Described is product from hardened thermoreactoplast.
EFFECT: obtaining curable composition containing divinyl aren dioxide, with increased storage life up to hardening and improved heat resistance after hardening.
