Synthesis, structure and catalytic properties of a novel zirconium guanidinato complex [Zr{ArNC(NMe2)N(SiMe3)}(μ2-Cl)Cl2]2[Ar=2,6-iPr2-C6H3]
摘要:
A novel non-symmetric zirconium guanidinato complex, [(Zr{ArNC(NMe2)N(SiMe3)}(mu(2)-Cl)Cl-2}(2)] (Ar = 2.6-Pr-i(2)-C6H3). was synthesized and structurally characterized. Catalytic studies showed that the zirconium complex was active for ethylene polymerization with the activity of 4.98 x 10(5) g PE/mol Zr h. The influences of cocatalysts, Al/Zr molar ratios and ethylene pressures on the activities were investigated. (c) 2007 Elsevier B.V. All rights reserved.
