The polymerization of ethylene with titanium complexes bearing one bulky imidazolin-2-iminato ligand (L) in the presence of MAO and/or TTPB as cocatalysts have been explored. The complex LTiCl3 and its methylated forms were prepared to shed light on the nature of the active polymerization species. With some of these complexes, the best catalytic activity was obtained at an Al:Ti ratio of 8.
研究了在 MAO 和/或 TTPB 作为共催化剂的存在下，带有一个大位阻的咪唑啉-2-亚氨基配体（L）的钛配合物引发乙烯聚合的情况。合成了配合物 LTiCl3 和其甲基化形式，以探究活性聚合物种的本质。对于其中一些配合物，在 Al:Ti 比为 8 时获得了最佳的催化活性。
