Titanium and zirconium complexes with eta(5): eta(1)-4-(alkyl/arylamino)(dimethyl)silylindene ligands as catalysts for ethene polymerization

摘要

First members of a novel family of constrained geometry complexes of titanium and zirconium containing a short bridge between the amide and inden-4-yl fragments were obtained. When activated with methylaluminoxane, these complexes can be used as highly active catalysts for ethene polymerization producing high-molecular-weight polymers.
