Popis:	A combination of low-angle and high-angle X-ray diffraction, H→D isotopic exchange and differential scanning calorimetry has been used to study the domain structure in Vitur T-0533 films. The changes in the characteristics of the domain structure of the film have been analysed to take account of their history. By studying the temperature dependence of the accessibility of the segmented polyurethane molecules to D 2 O, information could be obtained about the proportion of only slightly ordered formations and strong rigid-chain formation (domains) throughout the entire polymer volume.
