Post-Metallocenes: New Bis(pyrrolyl-2-aldiminato) Titanium Complexes for Ethylene Polymerization

Abstract

Abstract Two new bis(pyrrolyl-2-aldiminato) titanium complexes were synthesized and their structures determined by X-ray analyses. These complexes displayed high ethylene polymerization activity using MAO or Ph3C+B−(C6F5)4/iBu3Al as a cocatalyst. One of the complexes exhibited very high ethylene polymerization activity (14100 kg-polymer·mol-Ti−1·h−1) with very high molecular weight (Mv: 260.1 × 104) using MAO as a cocatalyst.
