  • High performance dewatering aids
    Patent number: 5405554
    Abstract: Water-soluble, branched, high molecular weight, cationic polymers are used in combination with low molecular weight, cationic polymers to provide the highly improved dewatering of suspended solids. Water-in-oil emulsions containing these cationic polymers in the aqueous phase are also described.
    Type: Grant
    Filed: February 8, 1990
    Date of Patent: April 11, 1995
    Assignee: Cytec Technology Corp.
    Inventors: Roger E. Neff, Joseph J. Pellon, Roderick G. Ryles
  • Preparation of aqueous polyacrylamide solutions for enhanced oil recovery
    Patent number: 4605689
    Abstract: A process is disclosed for converting polyacrylamide gel into dilute aqueous solutions suitable for use in secondary oil recovery. Polyacrylamide gel is initially converted into a slurry of small gel particles in water from which forms a homogeneous solution concentrate which is then readily diluted to give the final drive fluid without any significant polymer degradation. The process may additionally be adapted to the drilling site or to other on site operations requiring polyacrylamide solutions such as water treating, mining or paper making.
    Type: Grant
    Filed: November 28, 1984
    Date of Patent: August 12, 1986
    Assignee: American Cyanamid Company
    Inventors: John M. Witheford, Joseph J. Pellon, William P. Colman
  • Process for water-in-oil emulsions of water-soluble polymers
    Patent number: 4242247
    Abstract: Reduced coagulum is obtained when water-soluble monomers are polymerized in the dispersed phase of a water-in-oil emulsion and added salt is present in the aqueous monomer phase.
