Paper Title:
Prepare of Novel Zirconium Complex and Catalytic Performance for Ethylene Polymerization
  Abstract

Novel zirconium complex 2 has been prepared by treatment of the ligand complex 1 with ZrCl4•2THF in dichloromethane solution. The complex 1 and 2 were characterized by 1H-NMR and IR. Activated by MAO, Complex 2 displays very high activity for ethylene polymerization under the reaction temperature of 40~80 °C and the viscosity-average molecular weight of polyethylene is more than 3.0×104 when reaction temperature is no more than 60°C.The molecular-weight distribution measured by gel permeation reached 2.50.High melting points measured by DSC indicates that the polyethylene produced by complex 2 is high linearity and high crystallinity.
