ABSTRACT:
The invention relates to a process for the preparation of an olefin polymerisation catalyst component, said catalyst component and its use. The process is mainly characterized by the steps of(i) reacting in solution a magnesium compound containing an alkoxy group, a carboxylic acid halide and a four-valent titanium compound containing a halogen, for obtaining a dissolved reaction product and(ii) recovering a fraction of the reaction product from step (i) in particulate form by contacting the dissolved reaction product with a mixture of an aromatic and an aliphatic hydrocarbon, or by contacting the dissolved reaction product first with an aromatic hydrocarbon and then with an aliphatic hydrocarbon, the amount of aromatic and aliphatic hydrocarbon being at least 5 mol per mol of magnesium.
