The invention relates to a method for the preparation of a catalyst suitable for the polymerisation of an olefine by: a) bringing metallic magnesium into contact with a compound RX, R being an aromatic, aliphatic or cycloaliphatic group containing 1 to 20 carbon atoms and X being a halogen, and then b) bringing the obtained reaction product (I) into contact with an alkoxide and a Ti-containing compound, characterised in that an aromatic halogenide is used as the compound RX, an alkoxysilane-containing compound as the alkoxide and TiCl4 as the Ti-containing compound.
