Novel Iron(II) Complex as Single-Site Catalysts for Ethylene Polymerization

Abstract:

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 MSand ¹H-NMR and complex C₂ was characterized by MSand 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.
