ABSTRACT:
To prepare nitrogen-containing aromatic polymers, for example polyamides, polyimides and polybenzimidazoles, polyvalent aromatic carboxylic acids and aromatic diamines and/or aminocarboxylic acids or reactive derivatives thereof are reacted in a high-boiling inert solvent with the addition of a heat-stable dispersing auxiliary, and volatile by-products formed in this reaction are distilled off. When the reaction has ended, the batch is cooled and the polymer formed is filtered off.
