Abstract: The present invention relates to an inherently light- and heat-stabilized polyamide containing tetramethylpiperidine group of the general formula I being chemically bonded via nitrogen to a terminal polymer chain, wherein in the formula I the symbol R represents hydrogen, a hydrocarbon group containing 1 to 20 carbon atoms or a benzyl group, wherein it comprises 0.03 to 0.8 mole percent of tetramethylpiperidine, based on 1 mole of the polyamide polymer chain carboxamide groups. The invention further relates to a process for preparing such polyamide by polymerization in the presence of a tetramethylpiperidine derivative as well as the use of the polyamide for producing filaments, fibers or foils.
