Popis:	1. Dehydration (aromatization) of bis-adducts formed by Diels-Alder reaction between maleic anhydride and bisfuran compounds gives dianhydrides of aromatic tetracarboxylic acids with different structures, which are suitable for the preparation of thermostable polymers. 2. The nonaromatized bis-adducts can be used for the one-step preparation of polyimides and polyimidazopyrrolones in polyphosphoric acid, since they are aromatized under the polymersynthesis conditions.
