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, C¿1?-C20 alkyl, cycloalkyl, benzyl, OR?6¿ where R6 is H, C¿1?-C20 alkyl, cycloalkyl, benzyl; R?2, R3, R4, R5¿ independently of each other are C¿1?-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 R?1, R2, R3, R4 and R5¿. Said polyamides can be used to produce thread, fibres, films, flat structures and moulded bodies. |
