The layered structure of plastic parts injection-moulded from industrial polypropylenes under varying processing conditions was studied by scanning small-angle and wide-angle X-ray scattering measurements on cross-sections of the parts. The analysis of the data in terms of apparent crystallite sizes, several parameters characterizing the distribution and orientation of different types of crystallites, and long periods is demonstrated by means of selected representative examples.
