Abstract: The production of polyamides by polymerisation of normal monomers or oligomers is carried out in presence of 2,2,6,6-tetra-alkyl-piperidine derivative(s) substituted at position 4 with a functional group containing 1-4 amide-forming groups and optionally with a hydrocarbyl, hydroxyl or hydrocarbyloxy group on the ring nitrogen. A process for the production of polyamides comprises polymerization of the starting monomers or oligomers in presence of compound(s) of formula (I): in which: R = a functional group R with 1-4 amide-forming groups R (same or different); R = H, 1-20C alkyl, cycloalkyl, benzyl or OR ; R = H, 1-20C alkyl, cycloalkyl or benzyl; R -R = 1-10C alkyl; n = a whole number greater than 1. The piperidine units attached to R may or may not be identical with regard to the substituents R -R . Independent claims are also included for (a) polyamides obtained by this process; (b) filaments, fibers, film, sheet material and moldings containing these polyamides.

Abstract: Polyamide, whose main chain contains a chemically bound amine selected from the group consisting of 2-methyl-1,5-diaminopentane and 1-amino-2-R-cyclopent-1-ene, where R is a functional group capable of combining with an amino group to form an amide group, and processes for preparing such a polyamide and fibers, films and moldings comprising such a polyamide.
