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.

Abstract: The invention relates to a method for purifying 2,2,6,6-tetrasubstituted 4-amino-piperidines produced from the corresponding piperidin-4-ones, and subsequent distillation. According to the invention, the distilled 2,2,6,6-tetrasubstituted 4-amino-piperidine is reacted with hydrogen in the presence of a hydrating or dehydrating catalyst and the 4-amino piperidine is then separated from the reaction mixture.

Abstract: A process for purifying raw piperidines of formula (I), where R1 to R4 are C1 to C6 alkyl, R1 and R2 and/or R3 and R4 together are a CH2 chain with 2 to 5 C atoms. Said process is characterized in that in an initial step high-boiling-point substances and possible water are eliminated by distillation from the raw piperidines, in a second step 0.01 to 5 wt %, in relation to the product of the first step, of a reducing agent are added and in a third step the piperidines are isolated by distillation.
