Summary

The process of crystallization and the structure of poly/ oxymethylene/ (POM) films cast from hexafluoroacetone sesquihydrate solutions were studied. The supermolecular structure of thin POM films was studied by the use of polarization microscope. It has been found to consist mainly of spherulites, the size of which are essentially independent of the initial concentration of the solution. Similarly to the findings reported for thin films made of melts, ovoids and spiral ovodis were also found in minor amounts. Two additional formations indicating more complex structure were also detected. Further details of the structures formed could be recognized applying scanning electron microscopy.
