摘要：It was illustrated in this paper the successful synthesization of one α-diimine ligand and one new polycondensate ligand. The structure of the ligand was characterized by 1H NMR spectrum, and the structure of the polycondensate ligand was characterized by Thermogravimetric Analysis (TGA) and Element Analysis. Then these two ligands reacted with (DME)NiBr2 for the purpose of preparing α-diimine nickel complex and nickel coordination polymer characterized by Element Analysis and X-ray Photoelectron Spectroscopy (XPS). Then these two catalysts were adopted to facilitate ethylene polymerization and to compare the difference between them. It was found that the activities from nickel coordination polymer/MAO reached 106(g/molNi?h) and the molecule weights were about 105. ? Published under licence by IOP Publishing Ltd.
