Abstract

Complexes of the formula I, where M is an element of group 6 to 10 of the Period Table of the Elements, preferably Ni, can be used for the polymerization and copolymerization of olefins, for example in suspension polymerisation processes, gas-phase polymerization processes, bulk polymerization processes or emulsion polymerization processes.
