A PROCESS FOR THE PRODUCTION OF A LUBRICATING MATERIAL WHICH COMPRISES IRRADIATING A MIXTURE CONSISTING ESSENTIALLY OF C5 TO C20 SATURATED ALIPHATIC HYDROCARBONS WITH HIGH ENEERGY IONIZING RADIATION AT AN INITIAL INTENSITY ABOVE 4X10**7 EQUIVALENT ROENTGENS/HR. UNTIL THE TOTAL ENERGY ABSORBED IS ABOVE 80 B.T.U.''S/LB. AND THE VISCOSITY OF THE MIXTURE IS INCREASED TO ABOVE 40 S.S.U. AT 210*F., THEN DECRREASING THE RADIATION INTENSITY TO WITHIN THE RANGE OF 4X10**6 TO 4X10**7 EEQUIVALENT ROENTGENS/HR/. AND THEN FURTHER DECREASING THE RADIATION INTENSITY TO BELOW 4X10**6,
