Abstrakt: The results of studies of the oligomer-oligomer modification of epoxyamine compositions with amine adducts, oligomers, block oligomers, and oligocyclocarbonates differing in their structure and molecular weight upon hardening under the conditions of a general epoxide-amine polycondensation reaction, and competitive epoxide-amine and cyclocarbonate-amine reactions are given. The parameters of the structure and the elastic-deformation properties required for the preparation of high-quality thermally contracting epoxy polymers with a 'shape-memory' and for their reliable application are established.
