The invention relates to macromolecular compounds, to polyurethanes being prepared of isocyanates and containing macroheterocyclic fragments. Polyurethanes contain macroheterocyclic fragments in the main chain of polymer of general formula R4---OCHN-R1-CONH-R2-NHCOO-R3-OCONH-R2-NHCO--y-R4. A semipolymer with terminal isocyanate groups is subjected to interaction with macrochain extender in dimethylformamide solution. Dihydrazides of carboxylic acids and dihydrazides of disulphonyldibenzo-18(24)-crown-6(8) are used as macrochain extender.
