摘要:
This invention relates to a catalyst system containing bisiminopyridyl complexes of cobalt and/or iron with bulky substituents on the bisiminopyridyl ligand, to a method for the polymerization of &agr;-olefins, particularly ethylene, and to the use of the polyolefins which can be produced by said method for the production of moldings of all types.
摘要:
The invention relates to compounds having two metal centres, a process for preparing them, the use of the compounds as catalysts, a process for preparing homopolymers, copolymers and oligopolymers using these compounds, polymers obtainable from olefinic monomers and the compounds, the use of the polymers for shaped parts of all types and also shaped parts obtainable from these polymers.

The present invention relates to compounds containing vanadium in the oxidation state +III or +IV and one or more amido groups, a process for preparing these compounds, the use of the compounds of the invention for preparing a catalyst composition, a process for preparing the catalyst composition and also a process for preparing homopolymers and/or copolymers using the catalyst composition.
摘要:
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.
