Process for preparing nitrogen containing polymers |
| abstract |
For the production of nitrogen-containing aromatic polymers, e.g. As polyamides, polyimides and polybenzimidazoles, polyvalent aromatic carboxylic acids and aromatic diamines and / or aminocarboxylic acids or their reactive derivatives are reacted in a high-boiling inert solvent with the addition of a temperature-resistant dispersing agent and the resulting volatile by-products are distilled off. After the reaction has ended, the batch is cooled and the polymer formed is filtered off. |
