  • Polymers and process of making same
    Patent number: 4929687
    Abstract: Novel N-chloroamide polymers and a process for the production thereof are disclosed.
    Type: Grant
    Filed: May 5, 1986
    Date of Patent: May 29, 1990
    Assignee: American Cyanamid Company
    Inventors: Peter A. Jarovitzky, Yun-Lung Fu, Robin W. Dexter
  • Process for the preparation of N-haloamide polymers
    Patent number: 4785055
    Abstract: Aqueous solutions of polyacrylamides are acidified and then reacted with halogen gas or hypohalites to provide N-halogenated polymers. The product of the process are good wet strength additives for paper made from aqueous pulps of paper making fibers.
    Type: Grant
    Filed: June 23, 1987
    Date of Patent: November 15, 1988
    Assignee: American Cyanamid Company
    Inventors: Robin W. Dexter, Peter A. Jarovitzky, Yun-Lung Fu
  • Polyacrylamide and polyacrylic acid polymers
    Patent number: 4622356
    Abstract: The use of a cyclic compound containing a ##STR1## group, i.e., methone, has been found to allow a poor acrylamide or acrylic acid or 2-acrylamide-2-methylpropane sulfonic acid and its salts monomer to be polymerized to a polymer having improved performance characteristics and/or improved rates of polymerization. Optionally, urea is added with the methone.
    Type: Grant
