摘　　要：通过控制schiff碱缩合反应合成了三个桥联的α-苊二亚胺,进一步与无水氯化镍反应得到了新型双核桥联α-苊二亚胺镍催化剂,配体与催化剂经过1HNMR和质谱表征。在甲基铝氧烷(MAO)的存在下,显示出较高的催化活性,所得聚合物经GPC,DSC,13CNMR表征,结果显示聚合物具有较高的分子量,较低的熔点,以及较高的支化度。Three bridged α-Acenaphthenediimine ligands were prepared by controlled schiff reaction,and then reacted with anhydrous NiCl2 to give three novel binuclear bridged α-Acenaphthenediimine nickel complexes.Ligands and complexes were characterized by 1H NMR and MS.At the presence of MAO,these complexes showed high catalytic activity for ethylene polymerization.The characterization of polyethylene with GPC,DSC and 13C NMR showed that the polymer had higher Mw,Tm and branched degree.
