  • Water-based hydraulic fluids comprising poly-oxazines or poly-oxazolines
    Patent number: 4702854
    Abstract: Substantially oil-free aqueous industrial fluids possess superior lubricating and wear preventing characteristics and are useful as hydraulic fluids and metalworking compositions. Fluids of the invention comprise (1) an aqueous liquid and (2) a water-soluble synthetic addition copolymer of a poly-2-oxazoline or a poly-2-oxazine.The industrial fluids exhibit good Newtonian behavior and mechanical stability at high shear.
    Type: Grant
    Filed: May 2, 1983
    Date of Patent: October 27, 1987
    Assignee: The Dow Chemical Company
    Inventors: Kenneth L. Snyder, Jr., Syamalarao Evani
  • Water-based hydraulic fluids
    Patent number: 4493777
    Abstract: Substantially oil-free aqueous industrial fluids possess superior lubricating and wear preventing characteristics and are useful as hydraulic fluids and metalworking compositions. Fluids of the invention comprise (1) an aqueous liquid and (2) a water-soluble synthetic addition copolymer of (a) an ethylenically unsaturated crosslinking monomer, (b) an ethylenically unsaturated water-soluble monomer, and (c) an ethylenically unsaturated water-insoluble monomer.The industrial fluids exhibit good Newtonian behavior and mechanical stability at high shear.
    Type: Grant
    Filed: December 20, 1982
    Date of Patent: January 15, 1985
    Assignee: The Dow Chemical Company
    Inventors: Kenneth L. Snyder, Jr., James Peters
