摘要：

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)/(Bu3Al)-Bu-i 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 (M-v: 260.1 x 10(4)) using MAO as a cocatalyst.
