Abstract
A process for the preparation of a procatalyst suitable for preparing a catalyst composition for olefin polymerization, the procatalyst obtained or obtainable by the process; and a catalyst composition for olefin polymerization comprising the procatalyst. In particular a benzamide can be used as an activator in the preparation of a supported Ziegler-Natta type procatalyst useful for a process for the preparation of polyolefins. The Polyolefins and polypropylene homopolymers are also disclosed.
