FIELD: chemistry; technological processes.
SUBSTANCE: invention refers to the methods for preparing modified epoxy (meth) acrylates and their use as radically curable binders. Use of a modified epoxy (meth) acrylate resin, that is obtained using the method, at which the organic compounds containing epoxy groups are subjected to the exposure of (meth) acrylic acid in the presence of the suitable catalyst, and after at least 95 % of the epoxy groups have reacted, the product is subjected to partial reaction with anhydride of saturated dicarboxylic acids as binders in resin mixtures and compositions of mortars from the reactive polymeric resin, for example, for chemical hardening.
EFFECT: use of the specified modified epoxy (meth) acrylate resin allows the preparation of mortars, which are stable during storage, allowing to achieve good three-dimensional cross-linking and curing in the wide temperature range.
