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.

Abstract: The prodn. of polyamides (I) comprises polymerisation or polycondensation of the corresp. monomers in the presence of triacetone-diamine cpd(s). of formula (II). R = H or 1-20C hydrocarbyl, pref. 1-18C alkyl or benzyl. Also claimed are polyamides with inherent thermal stability, contg. a -NH-linked residue derived from (II) in the polymer chain. Also claimed is a process for the prodn. of filaments based on polycaprolactam modified with (II) as above, by melt spinning with take-off speeds of at least 4000 m/min. Also claimed are filaments obtd. by this process and fibres and sheet materials made from these filaments.

Abstract: Filaments with a relative viscosity RV of 2.0 to 3.0 (measured at a concentration of 1 g of fibres per 100 ml in a 96 wt % sulphuric acid) based on polycaprolactam, obtainable by: (a) extruding a melt consisting essentially of caprolactam through a spinning nozzle to form caprolactam filaments; (b) cooling the filaments thus produced and (c) drawing the cooled filaments off at a rate of at least [3600 + 1250.(3.0 - RV)] m/min, the polycaprolactam used being produced in the presence of at least one bicarboxylic acid from the group: C4-C10-alkane bicarboxylic acids, C5-C8-cycloalkane bicarboxylic acids, benzole and naphthaline bicarboxylic acids which may have up to two sulphonic acid groups and whose carboxylic acid groups are not adjacent, N-C1-C6-alkyl-N,N-di(C4-C10-alkane carboxylic acid)amine, 1,4-piperazine-di(C1-C10-alkane carboxylic acid), and a process for producing these filaments, their use for the production of fibers and flat products, and fibres and flat products made of these filaments.
