Complex compounds and their use in olefin polymerization

摘要

Complexes of the formulae I a to d, where M is an element of groups 6 to 10 of the Periodic Table of the Elements, preferably Ni, can be used for the polymerization and copolymerization of olefins, for example in suspension polymerization processes, gas-phase polymerization processes, bulk polymerization processes and emulsion polymerization processes.
