Abstract
The sulfide polymers of polyoxyalkylenes having the formula: ##STR1## wherein M is alkyl of from 1 to 4 carbon atoms, benzyl, phenyl, hydrogen or an alkali metal or ammonium ion; 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 1 to 50; n is an integer having a value of 1 to 30; and m has a value of from 2 to 10; and intermixtures of said polyoxyalkylene sulfide polymers. The above polymers have excellent antioxidating properties and are useful as synthetic metal working lubricants, antistatic agents and antioxidants for various other types of applications. They can also be used as crosslinking agents to impart oxidation resistance and static elimination.
