All lined up: C1-symmetric octahedral titanium complexes (see structure, Ti dark gray, N blue, O red, I purple) whose labile positions reside in different electronic environments were designed using the readily available salalen ligands. With methylalumoxane as co-catalyst, highly active catalysts were obtained, which yielded high-molecular-weight polypropylene with ultra-high isotacticities (see 13C NMR spectrum) and melting transitions.

Use of homogeneous catalytic systems which include as a pre-catalyst a complex of a Group IV metal and a salalen ligand in the polymerization of alpha-olefins, is disclosed. The alpha-olefin polymers obtained are characterized by controlled levels of tacticity. Also disclosed are novel salalen ligands and novel complexes thereof with Group IV metals.
