Résumé: The physical, mechanical and thermal properties of polyurethane produced by the reaction of urethane prepolymers with coordination compounds of copper were studied. The peculiarity of the used metal complexes is catalytic activity in the low-temperature dissociation of urethane groups and the ability to interact with the isocyanate groups with the subsequent formation of azoaromatic derivatives. It was found that when urethane prepolymers interacted with the bulky coordination compounds of copper the rigid blocks of coordination-related azo groups were formed which had a significant influence on the supramolecular organization of polyurethanes, and the complex of their physical and mechanical properties. It was shown that the metal complex structuring did not lead to a deterioration of the thermal stability of polyurethanes.
