  • Treatment of polyamide with gas phase of acid, anhydride or amine
    Patent number: 6448370
    Abstract: The end group content of polyamide in the solid state may be reduced by treating the polyamide with gas-phase acid, anhydride, or amine. Stain- or dye-resistant polyamide fibers can be made by reducing the number of amino end groups. Reduction in the number of carboxylic end groups reduces the rate of regeneration of starting monomers during extrusion.
    Type: Grant
    Filed: December 18, 2000
    Date of Patent: September 10, 2002
    Assignee: BASF Corporation
    Inventors: Otto M. Ilg, Harry Y. Hu, Scott R. Brank
