The invention relates to a method for producing polyamides, characterized in that the polymerisation of starting monomers or starting oligomers is carried out in the presence of at least one compound of formula (I), where R is a functional group R8 which has 1 to 4 identical or different amide-forming groups R7; R1 is H, C1-C20 alkyl, cycloalkyl, benzyl, OR6 where R6 is H, C1- C20 alkyl, cycloalkyl, benzyl; R2, R3, R4, R5 independently of each other are C1-C10 alkyl; n is a natural number greater than 1, and the piperidine derivatives linked to R are identical to or different from the substituents, that is R1, R2, R3, R4 and R5. Said polyamides can be used to produce thread, fibres, films, flat structures and moulded bodies.
Procédé de préparation de polyamides, selon lequel la polymérisation de monomères ou d'oligomères de départ est effectuée en présence d'au moins un composé de formule (I). Dans ladite formule, R représente un groupe fonctionnel R?8¿ portant 1 à 4 groupes R?7¿ formateurs d'amides, identiques ou différents, R?1¿ représente H, alkyle C¿1?-C¿20?, cycloalkyle, benzyle, OR?6¿, R?6¿ représentant H, alkyle C¿1?-C¿20?, cycloalkyle, benzyle, R?2¿, R?3¿, R?4¿ et R?5¿ représentent indépendamment l'un de l'autre alkyle C¿1?-C¿10?, n représente un nombre entier naturel supérieur à 1, les dérivés de pipéridine liés à R étant identiques ou différents des substituants comprenant R?1¿, R?2¿, R?3¿, R?4¿ et R?5¿. Lesdits polyamides peuvent être utilisés pour la fabrication de fils, fibres, feuilles, surfaces et produits moulés.
