摘要：

A total of 24 amido functionalized ansa half-sandwich dichloride complexes of titanium, zirconium and hafnium with cyclopentadienyl or indenyl ligands have been prepared, characterized and used for catalytic ethylene polymerization. Alkyl and omega -alkenyl substituents on the aromatic system influence the polymerization activity of the catalysts and the properties of the produced polyethylene. After activation with methylalumoxane the omega -alkenyl substituted catalysts show self-immobilization in ethylene polymerization. (C) 2001 Elsevier Science B.V. All rights reserved.
