Novel Iron(II) Complex as Single-Site Catalysts for Ethylene Polymerization
Novel iron (II) complex C2 has been prepared by treatment of the ligand C1 with FeCl2 in THF solution. The complex C1 was characterized by MS and 1H-NMR and complex C2 was characterized by MS and element analyze. Activated by MAO, complex 2 exhibites very high activity and produces high molecular weight polyethylene. The molecular weight distribution measured by gel permeation reached 2.1 to 2.4. the GPC profile of PE obtained and High melting points measured by DSC indicates indicates that the polyethylene produced by complex C2 is high linearity and high crystallinity.
