Abstract

An inherently light- and heat-stabilized polyamide has at least one piperidine compound bonded to the backbone polymer chain and at least one 4-amino-2,2,6,6-tetramethylpiperidine compound bonded to the backbone polymer chain. The inherently light- and heat-stabilized polyamide may be used to form articles such as, for example, fibers, carpets, yarns, and textile fabrics.
