ABSTRACT:
A polymerization process for olefins, diolefins and/or acetylenically unsaturated monomers is described. The monomers are contacted with an ionic catalyst which comprises a cyclopentadienyl derivative of Group IV-B metals as cation and a compatible non-coordinating anion containing a plurality of boron atoms. Borate, carborate, borane, carborane, metallaborane and metallacarborane compounds exemplify anion sources and dihydrocarbyl-substituted bis(cyclopentadienyl) zirconium compounds exemplify the Group IV-B metal cation sources.
