Investigation of the domain structure in segmented polyurethanes by means of small-angle x-ray scattering

Abstract Standard analytical procedures for SAXS investigations of isotropic samples with globular or “spongelike” inclusions use Porod's asymptotic law and the Porod invariant. In this work another method of analysis is presented which gives directly the volume fraction of the inclusions and the specific inner surface of the sample. Previously these values could only be obtained by performing other measurements in addition to SAXS.
