ABSTRACT:
Disclosed are selected poly(oxyalkylated) hydrazines of the formula: ##STR1## wherein R is selected from hydrogen, lower alkyl groups having from 1 to 4 carbon atoms, phenyl and mixtures thereof; and the sum of w, x, y, and z is from about 4 to about 20. These compounds are shown to be effective corrosion inhibitors for hydraulic fluids.
