Synthesis of Titanium (IV) Complexes with Schiff‐base Ligand and Their Catalytic Activities for Polymerization of Ethylene and Styrene

Reaction of titanium (IV) isopropoxide with the unusual land of Shiff‐base in 1:1 molar ratio gives a variety of new derivatives of titanium (IV) in high yield. These complexes were characterized by elemental analyses, IR, MS and ¹H NMR. It was noteworthy to find that all these complexes were active for polymerizations of ethylene and styrene when activated by a Lewis acid cocatalyst (MAO).
