METHOD OF OBTAINING AROMATIC POLYAMIDINES Russian patent published in 2014 - IPC C08G69/32

Abstract RU 2510633 C1

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining aromatic polyamidines, which can be used for obtaining heat-resistant film light-sensitive and luminescent materials. Method of obtaining polyamidines consists in realisation of polycondensation of 4,4'-dicarboxamidodiphenyloxide with aromatic diamines in mixture CH₃SO₃H:P₂O₅ (8-10:1 wt.), at 100-120°C, for 4-6 hours.

EFFECT: invention makes it possible to perform synthesis in milder conditions on the basis of stable and available monomers, and increase molecular weight of polymers.
