英文摘要	A series of 2,6-dibenzhydryl-N-(2-phenyliminoacenaphthylenylidene)-4-chloroanilines (L1-L5) and their nickel halide complexes LNiX2 (X = Br, C1-C5; X = Cl, C6-C10) were synthesized. All organic compounds were characterized by FT-IR and NMR spectroscopy and elemental analysis. The nickel complexes were characterized by FT-IR spectroscopy, elemental analysis and their structures were determined by single-crystal X-ray diffraction. Upon activation with MAO, all of these nickel complexes showed high activities (up to 10(7) g of PE (mol of Ni)(-1) h(-1)) for ethylene polymerization. The resulting polyethylenes possess high molecular weights (M-w up to 10(6) g mol(-1)) and feature high degrees of branching. The MM-QEq method was employed to assess the ligands' effects on catalytic activities. The results show that higher net charges on the nickel core correlate directly with higher measured activities.
