Abstract
The sulfur-containing polyoxyalkylenes having the formula: ##STR1## wherein E is --SW or a halogen atom; W is hydrogen, phenyl, alkyl of 1 to 4 carbon atoms, an alkali metal or ammonium ion, or a heterocyclic radical containing from 2 to 4 hetero atoms in a 5-or 6-membered ring which may be monocyclic or may be fused to an aromatic ring; A, C and D represent lower alkylene of 2 to 4 carbon atoms; B is alkylene of 2 to 8 carbon atoms; y and z are each integers having a value of 0 to 50; x is an integer having a value of from 2 to 50; and n is an integer having a value of from 1 to 30; and intermixtures of said polyoxyalkylenes. The above compounds display a wide variety of uses; however, all are active metal working lubricants. Additional fields of utility, which may vary in the degree of activity for the various members of the above group include liquid dispersants, emulsifiers, low foaming surfactants for paints, pigments and dyes, anti-static agents, mold release agents, heat transfer fluids and anti-oxidants.
