A series of [O−N(H)X]TiCl3 complexes derived from (arylamino)methylene phenol are prepared. The molecular structures of the complexes are characterized by 1H NMR, 13C NMR, and X‐ray analysis. Upon activation with modified methylaluminoxane (MMAO), the titanium complexes display high thermal stability and single‐site like ethylene (co)polymerization behavior at the temperatures of up to 150 °C. 1‐Octene
制备了一系列衍生自(芳基氨基)亚甲基苯酚的[O - N(H)X] TiCl 3配合物。配合物的分子结构通过1 H NMR,13 C NMR和X射线分析表征。用改性的甲基铝氧烷(MMAO)活化后,钛络合物在高达150°C的温度下显示出高的热稳定性和单中心乙烯(共)聚合行为。1-辛烯和1-辛烯被证明适合在110°C的温度下掺入聚乙烯主链中,最高活性为1.89×10 6 g / mol(Ti)·h·atm。X侧基对配合物PPh 2的催化行为有很大的影响。被证明是最优组。©2013 Wiley Periodicals,Inc.
