The instant invention relates to polyamides containing chemically bound UV-absorbers of the type oxanilide or benzylidene-malonate produced by co-condensation of the UV-absorbers with the prepolymeric compounds and to a process for the production of polyamides with improved mechanical properties wherein the prepolymeric compounds and the UV-absorbers are mixed prior to the condensation reaction and wherein the UV-absorbers are used in a concentration range of from 0.0001 to 5 % by weight, related to the prepolymeric compounds.The instant polyamides are especially suitable for the manufacture of fibres having improved mechanical properties.
