Title
(DE) VERFAHREN ZUR KONTINUIERLICHEN HERSTELLUNG VON POLYAMIDEN MIT VERBESSERTEN FLIESSEIGENSCHAFTEN
(EN) METHOD FOR CONTINUOUSLY PRODUCING POLYAMIDES HAVING IMPROVED FLOW PROPERTIES
(FR) PROCEDE DE PRODUCTION CONTINUE DE POLYAMIDES AUX PROPRIETES D'ECOULEMENT AMELIOREES
Abstract
(DE)
Die vorliegende Erfindung betrifft ein verbessertes Verfahren zur kontinuierlichen Herstellung von sternförmig verzweigten Polyamiden aus Lactamen und/oder Aminocarbonsäuren durch Zugabe der Verzweiger erst am Ende des Polymerisationsprozesses.
(EN)
The invention relates to an improved method for continuously producing polyamides, which are branched in a star-shaped manner, from lactams and/or amino carboxylic acids by adding the branching agents only at the end of the polymerization process.
(FR)
L'invention concerne un procédé amélioré de production continue de polyamides ramifiés en étoile, à base de lactames et/ou d'acides aminocarboxyliques, par adjonction des agents de ramification à la fin du processus de polymérisation.
