  摘要：

  一系列铁和钴卤化物配合物的合成、表征和乙烯聚合行为，LMXn (M = Fe, X = Cl, n = 2, 3, X = Br, n = 2; M = Co, X = Cl , n = 2)，据报道带有螯合 2,6-双（亚氨基）吡啶基配体 L [L = 2,6-(ArNCR1)2C5H3N]。X 射线衍射研究表明金属中心的几何形状是扭曲的四角锥体或扭曲的三角双锥体。用甲基铝氧烷 (MAO) 处理配合物 LMXn 导致高活性乙烯聚合催化剂将乙烯转化为高线性聚乙烯 (PE)。具有酮亚胺配体 (R1 = Me) 的 LFeX2 预催化剂比具有醛亚胺配体 (R1 = H) 的预催化剂活性高大约一个数量级。观察到 Fe 基酮亚胺催化剂的催化剂生产率在 3750-20600 g/mmol·h·bar 范围内，而 Co ketimine 系统的活性为 450-1740 g/mmol·h·bar。生产的聚合物的分子量

  The synthesis of new iron(Pi) diiminopyridine complexes and their heterogenization to give highly active ethene polymerization catalysts is described. The ligands are characterized by (HNMR)-H-1, (CNMR)-C-13 spectroscopy and GC/MS. The complexes are paramagnetic and were characterized by elemental analyses and mass spectrometry. The complexes were activated and heterogenized with a cocatalyst consisting of partially hydrolyzed trimethylaluminum (PHT) on silica gel and were used for ethene polymerization.The polymerization results and the polymer properties are presented. The influence of the catalyst structure, hydrogen and 1-hexene on the polymerization behavior is discussed. (C) 2002 Elsevier Science B.V. All rights reserved.
