摘要

Abstract

7-Trihydroquinolin-8-one was condensed with the corresponding benzidine to give

'-bis(5

7-trihydroquinolin-8-ylidene)-[1

1'-biphenyl]-4

4'-diamine derivatives (

L1-L3

). The ligands were reacted with two equivalents of NiCl

·6H

O in a mixture of EtOH and CH

to afford the corresponding dinickel(Ⅱ) chloride complexes (

Ni1-Ni3

). The organic compounds were completely characterized

whilst the bi-metallic complexes were characterized by FTIR spectra and elemental analysis. These nickel complexes exhibited high activities towards ethylene polymerization in the presence of either MAO or Me

AlCl

maintaining a high activity over a prolonged period. The obtained polyethylenes were confirmed as having low molecular weights by GPC analysis.
