Title:
CONSTRAINED GEOMETRY LIGANDS AND COMPLEXES DERIVED THEREFROM
Document Type and Number:
WIPO Patent Application WO2002057272
Kind Code:
A3
Abstract:
A novel constrained geometry titanium (II) diene complex and ligands of such complexes are described. The novel complex has an olefin polymerization activity substantially in excess of a defined activity standard characteristic of analogous prior art constrained geometry diene complexes. Methods for the synthesis of the novel, high-activity complexes are described.
