Popis:	The effect of the proportion of rigid blocks in segmented polyetherurethane ureas on their mechanical properties is studied. It is established that there are two critical points on the plots of the properties of the polymers against temperature, in which the nature of the behaviour of the system changes its character. It is shown by small angle X-ray scattering that at these points the type of supermolecular (domain) structure of the polyetherurethane urea changes.
