Abstract
The Small-angle X-ray scattering (SAXS) patterns of oriented LDPE (λ=1...5.7) were fitted by calculating the small-angle intensity for a structure consisting of a linear paracrystalline lattice built up by finite lamellar or cylindrical crystallites. The resulting data of the superstructure were compared with corresponding values from wideangle X-ray scattering. It is shown that it is impossible to get quantitative information about the superstructure of oriented polymers by using SAXS alone. Nevertheless, the qualitative transition of the crystals during orientation can be explained very well.
