Title (EN) METHOD FOR MAKING POLYAMIDES
(FR) PROCEDE DE FABRICATION DE POLYAMIDES
Abstract: front page image
(EN)The invention concerns a continuous method for making polyamides. The polyamides are of the type derived from diacids and diamines. The method comprises a process which consists in continuously mixing a compound rich in amine terminal groups and a compound rich in acid terminal groups and a step which consists in the polycondensation of said mixture. The invention also concerns the starting phase of said method, during which an aqueous solution is used comprising a mixture of monomers in substantially stoichiometric proportions.
(FR)L'invention concerne un procédé continu de fabrication de polyamides. Les polyamides sont du type de ceux obtenus à partir de diacides et de diamines. Le procédé comprend une opération de mélange en continu d'un composé riche en groupements terminaux amines et d'un composé riche en groupements terminaux acides et une opération de polycondensation à partir du mélange. L'invention se rapporte à la phase de démarrage d'un tel procédé, au cours de laquelle est utilisée une solution aqueuse comprenant un mélange de monomères en proportions sensiblement stoechiométriques.
