Small-angle and wide angle X-ray scattering studies were carried out on polymer thin films containing microcrystalline behenic acid. Measurements were made on samples in various optical states prepared by appropriate heat treatment. The results were consistent with the picture which presupposes the existence of voids around the crystallites when the composite film is in the opaque state. It was found that, upon cooling, molten behenic acid crystallizes in B or E polymorph, but not in C polymorph. It was concluded that the crystallization temperature for the C form is very low for small particles (0.2–2 μm) so that the molten BA, upon cooling, becomes unstable due to the formation of the crystalline state of the B form at a temperature above the crystallization temperature of the C-form.
