摘要

Abstract

A series of nickel(II)

-diimine complexes with strong electron-withdrawing carboxyl groups

having reactive hydrogen atoms

were prepared and used as precatalysts for ethylene oligomerization and/or polymerization. The influence of metal halides and ligand structure on the catalytic activity and properties of products was investigated. The results showed that nickel bromide was much more active than nickel chloride

and the substituents at the

ortho

-position of aryl ring had large influence on the properties of products. Therefore

the products ranging from liquid oligomers to polymers could be readily obtained by the variation of the substituents on the ligands and reaction conditions.
