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.
Claims10
Vanadium-imido-phosphoraneiminato compounds.
Compositions containing vanadium-imido-phosphoraneiminato compounds and an organometallic compound of Group 1, 2, 12 or 13 of the periodic system of the elements according to IUPAC 1985, wherein at least one hydrocarbon group in said organometallic compound is bonded directly to the metal atom via a carbon atom.
A catalyst comprising a composition containing vanadium-imido-phosphoraneiminato compounds and an organometallic compound of group 1, 2, 12 or 13 of the periodic system of the elements according to IUPAC 1985, wherein at least one hydrocarbon group in said organo-metallic compound is bonded directly to the metal atom via a carbon atom.
A process for the homo- or co-polymerization of olefins, optionally with one or more dienes, comprising the step of carrying out polymerization in the presence of a catalyst comprising a composition containing vanadium-imido-phosphoraneiminato compounds and an organometallic compound of Group 1, 2, 12 or 13 of the periodic system of the elements according to IUPAC 1985, wherein at least one hydrocarbon group in said organometallic compound is bonded directly to the metal atom via a carbon atom.
