A process is disclosed for improving the productivity of a supported polymerisation catalyst formed from a magnesium alkoxide which normally undergoes poor metathesis towards production of a magnesium halide support. The process comprises reacting the magnesium alkoxide with an alkoxysilane to form a different magnesium alkoxide which undergoes good metathesis at a temperature at or above the temperature at which the alcohol which is formed dissociates from the alkoxide. The resulting magnesium alkoxide is then subjected to metathesis to provide a supported polymerisation catalyst component for use in the polymerisation of olefins.
