合成了TiCl2[salphen(di-tBu)]，对其进行了表征，并将其用作丙烯、1-辛烯和10-十一烯-1-醇共聚乙烯的预催化剂。对钛配合物的x射线衍射研究表明，中心金属具有反式cl，顺式o，顺式n排列的扭曲八面体配位。与MAO结合的配合物具有中等的乙烯聚合催化活性。该催化剂不仅能使乙烯与极性单体（丙烯和1-辛烯）共聚，还能与极性单体（10-十一烯-1-醇）结合。在乙烯-co-1-辛烯聚合物中，13C NMR只检测到单个1-辛烯单元的插入。版权所有©2010 John Wiley & Sons， Ltd
TiCl2[salphen(di-tBu)] was synthesized, characterized and employed as pre-catalyst in ethylene homo- and copolymerization with propylene, 1-octene and 10-undecen-1-ol. X-ray diffraction study on the titanium complex revealed a distorted octahedral coordination of the central metal with a trans-Cl, cis-O, cis-N arrangement. The complex combined with MAO afforded moderate catalytic activities in ethylene polymerization. Furthermore the catalyst not only copolymerized ethylene with apolar monomer (propylene and 1-octene), but also possessed significant capability of incorporation with polar monomer (10-undecen-1-ol). Only single insertion of 1-octene unit in ethylene-co-1-octene polymer was detected by 13C NMR spectrum. Copyright © 2010 John Wiley & Sons, Ltd.
