Abstract: NOVEL SUBSTITUTED AND UNSUBSTITUTED POLOXYLAKYLENE BIS-THIOUREAS HAVING THE FORMULA:

R-NH-C(=S)-NH-CH(-Y)-CH2-(O-CH2-CH(-Y))X-NH-C(=S)-NH-R1

WHEREIN X IS A NUMBER FORM 1 TO 10, R AND R1 ARE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, ALKYL AND ALKENYL, Y IS HYDROGEN OR LOWER ALKYL, ARE USEFUL AS EXTREME PRESSURE LUBRICNATS IN METAL WORKING FLUIDS AND PARTICULARLY IN AQUEOUS TYPE FLUIDS. COMPOSITONS COMPRISING THE THIOUREAS AND A BOUNDARY LUBRICANT PROVIDE THE ANTI-WELD AND FRICTION REDUCTION PRPERTIES NECESSARY FOR HEAVY DUTY MACHINING.
