A process for preparing polyamides comprises polymerizing starting monomers or starting oligomers in the presence of at least one compound of the formula (I)whereR is a functional group R<8 >which bears 1-4 identical or different amide-forming groups R<7>,R<1 >is H, C1-C20-alkyl, cycloalkyl, benzyl or OR<6>, where R<6 >is H, C1-C20-alkyl, cycloalkyl or benzyl,R<2>, R<3>, R<4 >and R<5 >are independently C1-C10-alkyl,n is a natural number greater than 1, andthe piperidine derivatives attached to R are identical or different with regard to the substituents, meaning R<1>, R<2>, R<3>, R<4 >and R<5>.The polyamides are useful for preparing filaments, fibers, films, sheetlike structures and moldings.
