摘要： The invention concerns a process and device for producing high-viscosity or highly stabilized, reaction-stable polyamides, in particular polyamide 6, with reactive amino end groups of less than 50 &mgr;eq/g and for continuously demonomerizing polyamides. The object of the invention is to produce simply, reliably and economically a high-viscosity or highly stabilized reaction-stable polyamide, in particular polyamide 6, and if necessary to carry out continuous demonomerization. According to the invention, the molten polyamide is brought into intimate contact, or intimately mixed with preheated nitrogen in a reaction system in at least one stage and a specific dwell time is set for the melt in a liquid phase. During the production of polyamide 6, expelled lactam is processed and fed to a polymerization reactor.

摘要： The invention concerns a method of continuously producing polyamide 6 using recycled lactam from extraction and melt-demonomerizing stages. According to the invention, the cyclic oligomers present in the recycled lactam owing to the addition of .epsilon.-caprolactam (fresh lactam) are dissolved in the lactam as a function of the concentration of the oligomers in the product in use, at a dissolution temperature of between 120.degree. C. and 180.degree. C. The solution is then passed to a treatment, the solution preferably being introduced into a closed system and hydrolyzed in the fusible phase under pressure, at water contents of between 3 and 15% and temperatures ranging from 220 to 280.degree. C. With a constant low water content being set, the melt is then fed to the polymerization process in a further pressure stage incorporating a gas chamber (polymerizator).
