| titleOfInvention | Process for preparing aromatic polyamides of high¹hydrolysis resistance |
| abstract | The invention relates to a process for the preparation of aromatic polyamides having high resistance to hydrolysis, by reacting aromatic diamines in a conventional organic solvent and optionally in the presence of inorganic salts, in which the diamine having a water content of up to 25% by weight is dissolved in the organic solvent, which may likewise contain water, and the solution is subjected to vacuum distillation until a water content of the bottom product of < 100 ppm has been reached, and, if desired, the inorganic salts and then the dicarboxylic acid dichloride are subsequently added in a manner known per se and the condensation reaction is carried out and completed in a conventional manner. |
