FIELD: chemistry.
SUBSTANCE: proposed is a curable adhesive composition of epoxide resin which contains: (a) epoxide resin; (b) amphiphilic block-copolymer containing at least one block-segment compatible with epoxide resin and at least one block-segment incompatible with epoxide resin; where the incompatible block-segment contains at least one polyether structure provided that, the polyether structure of the said incompatible block-segment contains at least one or more alkylene oxide monomer links containing at least four carbon atoms; where the compatible block-segment contains at least one polyether structure; where the amphiphilic block-copolymer is present in the epoxide resin adhesive composition in such an amount that, when the said epoxide resin adhesive composition solidifies, bonding strength of the obtained hardened epoxide resin adhesive composition increases compared to epoxide resin composition without the said amphiphilic polyether block-copolymer; and (c) at least one hardening agent or hardening catalyst; and (d) a viscosity modifier. The invention also relates to a method of obtaining a curable epoxide resin adhesive composition, and two or more bases joined using the said adhesive composition.
EFFECT: invention improves impact viscosity of epoxide resins.
