  • Polymer compositions useful as dye complexing agents, and processes for preparing same
    Patent number: 6391995
    Abstract: Described are preferred processes for preparing quaternary amine polymers of good color, comprising preparing a free base amine polymer by polymerizing a free base amine monomer in the presence of a water-soluble azo initiator, and subjecting the resultant polymer to quaternization conditions. Also described are unique, water-soluble quaternary amine polymers obtainable by such processes, and dye complexing polymer blends useful in the manufacture of detergents.
    Type: Grant
    Filed: February 9, 2001
    Date of Patent: May 21, 2002
    Assignee: Reilly Industries, Inc.
    Inventors: Ramiah Murugan, Eric F. V. Scriven, James R. Stout, Stephanie Syler Metrick
