| 摘要: 合成和表征了2个锆的配合物：Bis[N-(3-tert-butylsalicylidene) allylaminato] zirconium dichloride (4)和Bis[N-(3-tert-butylsali-cylidene)-iso-butylaminato] zirconium dichloride (5)，并且得到了配合物4的单晶结构。在引发剂的作用下，配合物4和苯乙烯进行自由基共聚，得到高分子化催化剂6。在助催化剂MMAO的存在下，4，5和6都可以催化乙烯聚合。最高活性为3.7×106 g PE·(mol Zr)-1·h-1。 |

| Abstract: Two zirconium complexes, Bis[N-(3-tert-butylsalicylidene) allylaminato] zirconium dichloride (4) and Bis[N-(3-tert-butylsalicylidene)-iso-butylaminato] zirconium dichloride (5), were prepared and characterized. The molecular structure of complex 4 has been determined by X-ray crystallographic analysis. The corresponding polymer-incorporated zirconium catalyst 6 was obtained by the co-polymerization of the olefin group of catalyst 4 with styrene in the presence of a radical initiator. All catalysts (4, 5 and 6) have been investigated for ethylene polymerization. These catalysts exhibit high activity up to 3.7 × 106 g PE·(mol Zr)-1·h-1 in the presence of modified methylaluminoxane (MMAO) as a co-catalyst. CCDC: 249504, 4. |
