Abstract
In order to achieve high catalytic activity during the homopolymerisation or copolymerisation of olefins by the Ziegler method, the active catalyst components - a compound of a metal of Group IVB to VIB of the Periodic System and an organometallic compound of a metal of Group IA to IIIA of the Periodic System - are supported on a mixed catalyst support comprising a substantially inert inorganic or organic first component and magnesium chloride which has been deposited thereon from a solution in a usually alcohol solvent which has evaporated off. Suitable first components include gamma-alumina, silica-alumina and styrene/divinyl benzene copolymer.
