METHOD OF PRODUCING N-PHENYL-SUBSTITUTED ACYCLIC POLYIMIDES Russian patent published in 2012 - IPC C08G73/10 

FIELD: chemistry.

SUBSTANCE: disclosed is a method of producing N-phenyl-substituted acyclic polyimides, involving reaction of aromatic imidoyl chlorides with dicarboxylic acids of formula HOOC-R'-COOH, where R' = n-C₆H₄, m-C₆H₄, (n-C₆H₄)₂O at 120-140°C for 6-9 hours.

EFFECT: obtaining N-phenyl-substituted acyclic polyimides based on stable, non-toxic and readily available monomers, considerable increase in molecular weight of the polymer, which enables to obtain strong film and moulding materials.
