    Abstract: Biscyclopentadienyl, Group 4 transition metal complexes are formed by contacting a biscyclopentadienyl Group 4 metal halide, hydrocarbyl, hydrocarbyloxy or amide complex with a conjugated diene. Uniquely, the ansa-rac diastereomer is selectively isolated and may be reconverted to the halide form if desired. When combined with standard activating cocatalysts or activated with an activating technique, the complexes form catalysts for polymerizing olefins, diolefins and/or acetylenically unsaturated monomers.

    Abstract: Boratabenzene cocatalysts, especially novel pentafluorophenyl boratabenzenes, are useful cocatalysts or activators with metallocenes. They are less expensive than prior art activators, are soluble and offer more irreversible reactions. Compositions comprise at least one metallocene catalyst and at least one dihydroboratabenzene or anion thereof. Processes include polymerizations with metallocenes in the presence of boratabenzene cocatalyst and activation process including bulk electrolysis techniques.
