Abstract

A process for the preparation of an inert oxide supported metal halide organo aluminium compound catalyst. The catalyst is obtained by reacting an activated support having surface hydroxyl groups with aluminium chloride selected from aluminium chloride solution and aluminium chloride vapors. A solution of an aluminium alkyl is added to the reacted support. The solvent is removed and the reacted support is dried.
