Abstract: The disclosure is a process for preparing polyamides by concentrating the wash water extract from the extraction of polyamide to an extractables content of not more than 85% by weight, adding fresh lactam down to a water content of from 0.5 to 13% by weight, and effecting at least one adiabatic expansion during the polymerization.

Abstract: The invention relates to a method for producing polyamides, characterized in that the polymerisation of starting monomers or starting oligomers is carried out in the presence of at least one compound of formula (I), where R is a functional group R8 which has 1 to 4 identical or different amide-forming groups R7; R1 is H, C1-C20 alkyl, cycloalkyl, benzyl, OR6 where R6 is H, C1C20 alkyl, cycloalkyl, benzyl; R2, R3, R4, R5 independently of each other are C1-C10 alkyl; n is a natural number greater than 1, and the piperidine derivatives linked to R are identical to or different from the substituents, that is R1, R2, R3, R4 and R5. Said polyamides can be used to produce thread, fibres, films, flat structures and moulded bodies.

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.
