  • Process and device for continuous production of polyamides
    Patent number: 6107449
    Abstract: A process and a device for continuous production of polyamides from a monomer starting material consisting (up to 100%) of adipic acid hexamethylene diamine and water are described. The process is characterized by completing of the first step under pressure at temperatures between 180 and 280.degree. C. in a closed reactor, after which the polyamide is subjected to further steps at the start of each of which vaporized water is removed or driven out by an inert gas.
