METHOD OF OBTAINING AROMATIC ACYCLIC POLYAMIDES Russian patent published in 2015 - IPC C08G73/10

Abstract RU 2552523 C1

FIELD: chemistry.

SUBSTANCE: method of obtaining aromatic acyclic polyamides consists in the following: interaction of aromatic dinitriles with aromatic dicarboxylic acids is realised at temperature 190-200°C for 8-14 hours. Reaction is carried out in ionic liquids of type 1-Bu-3-MeImCl/AlCl₃, 1-Et-3-MeImCl/AlCl₃, 1-Bu-2,3-Me₂ImCl/AlCl₃, 1-Bu-3-MeImBr, 1-Bu-3-MeImBF₄.

EFFECT: invention makes it possible to obtain polyamides with high molecular weight, good solubility and high thermal stability.
