        Thermal, noncatalytic polymerization of 1-olefins produces excellent lubricating oils.  Reaction conditions are 600°-650° F., reaction time about 10 hr., and pressures of 250-500 p.s.i.  The preferred range of 1-olefins is from hexene to dodecene.  Such olefins from any source, as cracked paraffin wax or Fischer-Tropsch products, can be used for the synthesis.
