Abstract:
Specific iron complexes (A), a catalyst system for polymerization of olefins comprising at least one metal complex (A) and/or (A′), a prepolymerized catalyst system, the use of these catalyst systems for the polymerization of olefins, and a process for the preparation of polyolefins by polymerization or copolymerization of olefins in the presence of one of the described catalyst systems.
