Title
(DE) VERWENDUNG VON HETEROGENKATALYSATOREN IN VERFAHREN ZUR HERSTELLUNG VON POLYAMIDEN

(FR) UTILISATION DE CATALYSEURS HETEROGENES DANS DES PROCEDES DE PRODUCTION DE POLYAMIDES
Abstract
(DE)
Beschrieben wird die Verwendung von Metalloxiden als Heterogen-Katalysatoren in einem Verfahren zur Herstellung von Polyamiden durch Polymerisation von Lactamen und gegebenenfalls weiteren polyamidbildenden Monomeren, bei dem die Metalloxide in einer Form eingesetzt werden, die die mechanische Abtrennung aus dem Reaktionsgemisch erlaubt, und im Verlauf oder nach Ende der Polymerisation aus dem Reaktionsgemisch entfernt werden, zur Verringerung des Gehaltes an extrahierbaren Verbindungen im erhaltenen Polyamid.
(EN)
The invention relates to the use of metal oxides as heterogeneous catalysts in a method for the production of polyamides by polymerization of lactams and possibly other polyamide-forming monomers. According to said method the metal oxides are used in a form which permits their mechanical separation from the reaction mixture and during or at the end of polymerization are separated from the reaction mixture so as to reduce the content of extractable compounds in the polyamide obtained in this way.
(FR)
L'invention concerne l'utilisation d'oxydes métalliques comme catalyseurs hétérogènes dans un procédé de production de polyamides par polymérisation de lactames et éventuellement d'autres monomères pouvant former des polyamides, procédé selon lequel les oxydes métalliques sont utilisés sous une forme permettant une séparation mécanique du mélange réactionnel, et sont éliminés du mélange réactionnel au cours ou à l'issue de la polymérisation, pour réduire la teneur en composés extractibles dans le polyamide obtenu.
