    摘要: Metallocycle metallocenes are produced by reacting a first metallocene having an aralkyl group or an aryl dialkyl silyl group attached to a cyclodienyl group with about two molar equivalents of an alkali metal alkyl having at least 4 carbon atoms. The use of the metallocycle metallocenes as components of catalyst for the polymerization of olefins is also disclosed.

    摘要: Novel catalyst systems which comprise 2-pyridine carboxaldimine nickel dihalide complexes can be used with an organoaluminum cocatalyst in slurry oligomerization or polymerization processes to oligomerize or polymerize mono-1-olefins and, optionally a higher alpha-olefin comonomer, to produce low molecular weight polymers or synthetic oils.
