ABSTRACT:
Novel organic-solvent-soluble nickel bis-diorgano-orthophosphates are prepared by the reaction of certain simple salts or esters of divalent nickel with certain non-aromatic triorgano orthophosphates free of aliphatic unsaturation. The simple salts or esters include preferably the halides, nitrates and acetates of divalent nickel.
These novel compounds, preferably in solution, are used as catalysts. When used in conjunction with alkyl aluminum halides, controlled oligomerization of ethylene, propylene and other olefins is achieved with the formation of polymers with low degrees of polymerization, e.g. 2 to 10, preferably no more than about 6 mers. When certain vanadium catalysts are added to these combined catalysts, high polymers of such monomers are achieved with significant residual aliphatic unsaturation.
