It is established that the functionality and structure of CCs influence on the adhesive, technological, and operational characteristics of modified epoxyamine compositions. It is shown how the interaction of cyclocarbonates with excess amines can produce prepolymers with different structure and molecular weight with NH<sub>2</sub>-end groups, and, when curing them with bisphenol diglycidyl ether, it is possible to create hybrid hydroxyurethane/epoxides with a controlled structure (architecture).
