METHOD OF PREPARING LONG CHAIN ALKYL AROMATIC HYDROCARBONS WHICH COMPRISES CONTACTING AN ALPHA OLEFIN IN DRY STATE AT A TEMPERATURE IN THE RANGE OF 0-50*C. WITH AN ANHYDROUS CATALYST SYSTEM COMPRISING AN ALKYLATABLE-AROMATIC HYDROCARBON CONTAINING A CATALYTIC MIXTURE OF (1) A TITANIUM HALIDE IN WHICH THE TITANIUM HAS A VALENCE OF AT LEAST THREE AND WHEREIN THE HALOGEN IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE AND BROMINE AND (2) AN ALUMINUM COMPOUND SELECTED FROM THE GROUP CONSISTING OF ALKYL ALUMINUM DIHALIDES, DIALKYL ALUMINUM HALIDES AND ALKYL ALUMINUM SESQUIHALIDES WHEREIN THE HALOGEN IS SELECTED FROM THE GROUP CONSISTING OF CHLORINE AND BORMINE, WHEREBYY THE ALPHA OLEFIN IS POLYMERIZED TO A LONG CHAIN OLEFIN WITHOUT SUBSTANTIAL REACTION OF SAID AROMATIC HYDROCARBON, AND THEN CONTACTING THE REACTION MIXTURE WITH A DRY HYDROGEN HALIDE SELECTED FROM THE GROUP CONSISTING OF HYDROGEN CHLORIDE AND HYDROGEN BROMIDE IN AMOUNT OF AT LEAST 0.5 MOLE PEER MOLE OF SAID ALUMINUM COMPOUND, WHEREBY SAID LONG CHAIN OLEFIN ALKYLATES THE AROMATIC HYDROCARBON.
