  Biphenyl-Bridged 6-(1-Aryliminoethyl)-2-iminopyridylcobalt Complexes: Synthesis, Characterization, and Ethylene Polymerization Behavior

  摘要：

  A series of biphenyl-bridged 6-(1-aryliminoethyl)-2-iminopyridine derivatives reacted with cobalt dichloride in dichloromethane/ethanol to afford the corresponding binuclear cobalt complexes. The cobalt complexes were characterized by FT-IR spectroscopy and elemental analysis, and the structure of a representative complex was confirmed by single-crystal X-ray diffraction. Upon activation with either MAO or MMAO, these cobalt complexes performed with high activities of up to 1.2 x 10(7) g (mol of Co)(-1) h(-1) in ethylene polymerization, which represents one of the most active cobalt-based catalytic systems in ethylene reactivity. These biphenyl-bridged bis(imino)pyridylcobalt precatalysts exhibited higher activities than did their mononuclear bis(imino)pyridylcobalt precatalyst counterparts, and more importantly, the binuclear precatalysts revealed a better thermal stability and longer lifetimes. The polyethylenes obtained were characterized by GPC, DSC, and high-temperature NMR spectroscopy and mostly possessed unimodal and highly linear features.

  带有N，N'-双（1-（6-（1-（6-（1-（芳基））乙基）吡啶-2-基）亚乙基）联苯胺的双核铁配合物的合成，表征和乙烯聚合行为†

  摘要：

  已经合成并充分表征了一系列的N，N′-双（1-（6-（1-（芳基氨基）乙基）吡啶-2-基）亚乙基）联苯胺及其双金属铁配合物。当被MAO或MMAO活化时，所有的铁络合物对于乙烯的聚合均表现出高达1.3×10 7 g mol -1（Fe）h -1的高活性。与它们的单核对应物相比，这种双金属配合物不仅在升高的温度（高达70°C）下保持相对较高的活性，而且还显示出更长的使用寿命。所得聚乙烯通过GPC，DSC和高温NMR光谱表征，表明具有多峰和高度线性特征。
