A PROCESS FOR PREPARING POLYAMIDES COMPRISES POLYMERIZING STARTING MONOMERS OR STARTING OLIGOMERS IN THE PRESENCE OF AT LEAST ONE COMPOUND OF THE FORMULA (1) (FORMULA I) WHERE R IS A FUNCTIONAL GROUP R8 WHICH BEARS 1-4 IDENTICAL OR DIFFERENT AMIDE-FORMING GROUPS R7, RL IS H, CL-C20-ALKYL, CYCLOALKYL, BENZYL OR OR6, WHERE R6 IS H, CL-C20-ALKYL, CYCLOALKYL OR BENZYL R2, R3, R4 AND R5 ARE INDEPENDENTLY C1-CL0-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 RL, R2, R3, R4 AND R5.THE POLYAMIDES ARE USEFUL FOR PREPARING FILAMENTS, FIBERS, FILMS, SHEETLIKE STRUCTURES AND MOLDINGS.
