Catalysts, method of preparing these catalysts, and polymerization processes wherein these catalysts are used |
摘要 |
An ionic catalyst useful for the polymerization of olefins, diolefins and/or acetylenically unsaturated monomers is described. The catalyst comprises cyclopentadienyl derivatives 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. Utility is illustrated for olefin polymerization.
