METHOD FOR PREPARING OLEFIN POLYMERS OF THE C10C24 RANGE WHICH COMPRISES CONTACTING ANALPHA OLEFIN AT A TEMPERATURE IN THE RANGE OF -30 TO +15*C. WITH A CATALYST SYSTEM COMPRISING A C6-C10 AROMATIC HYDROCARBON, WHICH HAS NO MORE THAN TWOALKYL SUBSTITUENTS, CONTAINING A CATALYTIC MIXTURE OF (1) A TITANIUM TETRAHALIDE IN WHICH THE HALOGEN IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE AND BROMINE, (2) AN ALUMINUM COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALKYL ALUMINUM DIAHLIDES,DIALKYL ALUMINUM HALIDES AND ALKYLALUMINUM SEQUIHALIDES WHEREIN THE HALOGEN IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE AND BROMINE, AND (3) A POLYETHER SELECTED FROM THE GROUP CONSISTING OF ETHYLENE GLYCOL DIMETHYL ETHER, DIETHYLENE GLYCOL DIMETHYL ETHER, TRIETHYLENE GLYCOLDIMETHYL ETHER AND TETRAETHYLENE GLYCOL DIMETHYL ETHER, THE TITANIUMTETRAHALIDE AND ALUMINUM COMPOUND BEING SUCH THAT THE ATOMIC RATIO OF AL TO TI IS IN THE RANGE OF 0.1-1.0 AND THE AMOUNT OF POLYETHER BEING SUCH THAT THE ATOMIC RATIO OF O TO AL IS IN THE RANGE OF 0.2-1.6, AND SEPARATING OLEFIN POLYMERS OF THE C10-C24 RANGE FROM THE REACTION MIXTURE.
