Abstract

A new method was suggested for preparing aromatic polyphenylquinazolones by thermal polyhet-erocyclization of polyamidines containing free carboxy groups. The structure of the polyphenylquinazolones obtained was confirmed by elemental analysis and IR spectroscopy. The polymers obtained are soluble in a wide range of organic solvents and resistant to thermal and thermal oxidative degradation; they exhibit high deformation and strength characteristics. Such properties make these polymers promising for processing into various items by traditional methods.
