THE METHOD OF PREPARING HIGH VISCOSITY SYNTHETIC LUBRICATING OILS FROM ALPHA-OLEFINS HAVING THE STRUCTURAL FORMULA R-CH=CH2 WHEREIN R IS AN ALKYL RADICAL CONTAINING FROM 4 TO 14 CARBON ATOMS WHICH COMPRISES CONTACTING THE ALPHA-OLEFIN FOR A TIME RANGING FROM 1 MINUTE TO 2 HOURS WITH A CATALYST COMPRISING A TITANIUM HALIDE COMBINED WITH AN ORGANO ALUMINUM COMPOUND HAVING THE FORMULA AIR''NX3-N, WHEREIN AL IS ALUMINUM, R'' IS A HYDROCARBYL GROUP, X IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN AND HALOGEN, AND N IS AN INTEGER FROM 1 TO 3, WHEREIN THE TITANIUM TO ALUMINUM ATOMIC RATIO OF THE CATALYST RANGES FROM 1:1 TO 1:20 TO PRODUCE NORMALLY SOLID POLYMERS, THEREAFTER ADDING A SUFFICIENT QUANTITY OF SAID TITANIUM HALID TO ADJUST SAID TITANIUM TO ALUMUNIM ATOMIC RATIO OF THE CATALYST TO WITHIN THE RANGE FROM 2:1 TO 20:1 AND CONTINUING THE CONTACTING FOR AN ADDITIONAL TIME RANGING FROM 1 HOUR TO 16 HOURS TO PRODUCE NORMALLY LIQUID POLYMERS.
