Abstract :
Thermostable polyimides based on perylenetetracarboxylic dianhydride and aromatic diamines containing oxadiazole rings were prepared and thin films were made therefrom. Dark-red, opaque coatings resulted having strong adhesion to the glass support. The composition of these polyimide films was analysed using X-ray photoelectron spectroscopy (XPS). The dynamo-mechanical and dielectric behaviour of the polyimide films were investigated, as well.
