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.
