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.
