摘要：
Novel iron (II) complex C-2 has been prepared by treatment of the ligand C-1 with FeCl2 in THF solution. The complex C-1 was characterized by MS and H-1-NMR and complex C-2 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 C-2 is high linearity and high crystallinity.
