Abstract

The present invention relates to vanadium-imido-phosphoraneiminato compounds, to compositions containing vanadium-imido-phosphoraneiminato compounds, which compositions are suitable especially as catalysts for the polymerization of olefins, especially for ethylene/propylene or ethylene/α-olefin copolymerization and the terpolymerization of those monomers with dienes.
