Abstract

The new binuclear phenoxyiminato zirconium complex {1,7-(O)₂C₁₀H₄-2,7-[CH=N(2,6-ⁱPr₂C₆H₃)]₂}Zr₂Cl₆(THF)₂ (FI²-Zr₂) polymerizes ethylene with greater activity (8×) than the mononuclear analogue. Also, this catalyst produces high molecular weight ethylene + 1-hexene copolymers, while the mononuclear analogue yields only traces of copolymer under identical conditions. This ability to produce copolymers suggests cooperativity between the two Zr centers which promotes 1-hexene co-enchainment.
