Abstract: The present invention relates to a process for the preparation of a procatalyst suitable for preparing a catalyst composition for olefin polymerization, said process comprising the steps of: Step A) providing or preparing a Grignard compound; Step B) contacting the Grignard compound with a silane compound to give a first intermediate reaction product being a solid support; Step C) activating said solid support, comprising two sub steps: Step C1) contacting the solid support obtained in step B) with at least one first activating compound and a second activating compound; and Step C2) a second activation step by contacting the activated solid support obtained in step C1) with an activating electron donor; to obtain a second intermediate reaction product; Step D) reacting the second intermediate reaction product obtained in step C) with a halogen-containing Ti-compound, optionally an activator and at least one internal electron donor in several sub steps to obtain said procatalyst. The invention moreover relates to a procatalyst, a catalytic system comprising said procatalyst and to a process to prepare polyolefins using said catalyst system and the polyolefins obtained therewith.
