Abstract
A novel non-symmetric zirconium guanidinato complex, [{Zr{ArNC(NMe2)N(SiMe3)}(μ2-Cl)Cl2}2] (Ar = 2,6-iPr2-C6H3), was synthesized and structurally characterized. Catalytic studies showed that the zirconium complex was active for ethylene polymerization with the activity of 4.98 × 105 g PE/mol Zr h. The influences of cocatalysts, Al/Zr molar ratios and ethylene pressures on the activities were investigated.
