合成了两种新的双（吡咯-2-氨基吡啶）钛配合物，并用x射线分析确定了它们的结构。这些配合物以MAO或Ph3C+B−(C6F5)4/iBu3Al为助催化剂表现出较高的乙烯聚合活性。其中一种配合物以MAO为助催化剂，具有很高的分子量（Mv: 260.1 × 104）和14100 kg-polymer·mol-Ti−1·h−1的乙烯聚合活性。
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.
