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.
