Abrégé
(EN)
The invention relates to a process for producing an aromatic polyimide, comprising the following steps: (a) preparing one or more salt(s) by reacting one or more aromatic tetracarboxylic acid(s) in the solid state and one or more diamine(s), optionally in the presence of one or more chain limiter(s), in the presence of one or more binder(s), comprising one or more organic liquid(s), in an amount of from 1% to 25% by weight relative to the total weight of the aromatic tetracarboxylic acid(s), of the diamine(s) and of the optional chain limiter(s), then; (b) polymerising the salt(s) obtained in step (a).

L 'invention concerne un procédé de fabrication d 'un polyimide aromatique, comprenant les étapes suivantes : (a) préparation d'un ou plusieurs sel(s) en faisant réagir un ou plusieurs acide(s) tétracarboxylique(s) aromatique(s) à l ' état solide et une ou plusieurs diamine(s), optionnellement en présence d'un ou plusieurs limiteur(s) de chaînes, en présence d'un ou plusieurs liant(s), comprenant un ou plusieurs liquide(s) organique(s), en une quantité de 1 à 25 % en poids par rapport au poids total du ou des acide(s) tétracarboxylique(s) aromatique(s), de la ou des diamine(s) et du ou des limiteur(s) de chaînes éventuel(s), puis; (b) polymérisation du ou des sel(s) obtenus à l ' étape (a).
