titleOfInvention |
Organometallic complexes comprising phosphonite ligands, and their use in catalyzing olefin oligomerization |
abstract |
A catalytic composition for oligomerizing olefins, in particular ethylene, comprises mixing at least one nickel complex, prepared by reacting a nickel salt with a phosphonite ligapd, with at least one hydrocarbylaluminum compound in a molar proportion with respect to the nickel of not more than 8″ and selected from the group formed by tris(hydrocarbyl)aluminum compounds, chlorinated or brominated hydrocarbylaluminum compounds and aluminoxanes. |
