摘要： A novel process for the manufacture of a mixed catalyst system by combining a Ziegler catalyst and a tridentate iron complex is described, which is characterized in that the reaction of a tridentate ligand with an iron compound is performed in an organic solvent containing less than 10 percent by weight, based on the total amount of the organic solvent, of electron donor compounds selected from the group consisting of ethers, aliphatic esters, aromatic esters, tertiary amines, amides, silanes, silazanes or orthoesters.
