  • Single-phase or multi-phase continuous polyamide polymerization processes
    Patent number: 6759505
    Abstract: There is provided a process for the continuous polymerization of polyamides which is carried out under conditions of pressure, temperature and polymer concentration in water that will ultimately yield multiple phases (including a second liquid polymer phase or a polymer precipitate). However, a single phase operation is achieved under these conditions by appropriate management of residence time and using a well-mixed reaction environment in early stages of the polymerization.
    Type: Grant
    Filed: September 28, 2001
    Date of Patent: July 6, 2004
    Assignee: E. I. du Pont de Nemours and Company
