Abstract

Procedure for the preparation of diamides of aromatic and cycloaliphatic dicarboxylic acids by ammonolysis of an oligoester or polyester of the corresponding dicarboxylic acid with a multivalent alcohol, characterized in that the ammonolysis is carried out in a multivalent alcohol at temperatures of 30 to 200ºC and partial pressures of ammonia 0.1 to 50 absolute atmospheres.
