Abstract: Zpusob výroby polyamidu spocívá v tom, ze se polymerizace výchozích monomeru nebo výchozích oligomeru provádí za prítomnosti alespon jedné slouceninyvzorce (I), ve kterém znací R funkcní skupinu R.sup.8.n., která nese 1 az 4 stejné nebo rozdílné amidotvorné skupiny R.sup.7.n.; R.sup.1.n. je H, C.sub.1.n. az C.sub.20.n.-alkyl, cykloalkyl, benzyl, OR.sup.6.n., kde znací R.sup.6.n. H, C.sub.1.n. azC.sub.20.n.-alkyl, cykloalkyl, benzyl; R.sup.2.n., R.sup.3.n., R.sup.4.n., R.sup.5.n. jsou nezávisle na sobe C.sub.1.n. az C.sub.20.n.-alkyl; n je prirozené císlo vetsí nez 1, pricemz piperidinové deriváty vázané na R jsou se zretelem na substituenty, to znamená R.sup.1.n., R.sup.2.n., R.sup.3.n., R.sup.4.n. a R.sup.5.n., rozdílné nebo stejné. Takto vyrobené polyamidy se pouzívají k výrobe nití, vláken, fólií, plosných útvaru a tvarových teles.

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.
