摘要：
The structure of new polyurethanes based on (macro)heterocyclic compounds and the relation between the inversion of IR dichroism of polyurethanes and the orientational phenomena and the mechanism of deformation of polyurethanes differing in the level of supramolecular organization were studied. The comparative examination of transmission IR spectra and multiple attenuated total reflectance IR spectra combined with the results of polarization measurements under deformation of film samples provides evidence that the studied polymers feature different supramolecular organizations.
