摘要：

We report here that (η5-indenyl)trichlorotitanium (IndTiCl3) activated with MAO is a catalyst exceedingly high in both A and specificity and which is relatively insensitive to polymerization conditions). We have synthesized IndTiCl3 in 96% yield, obtained its X-ray structure, and demonstrated that it possesses unusually high activity and syndioselectivity in styrene polymerizations which are relatively insensitive to Tp, catalyst concentration, and [Al]/[Ti]. These are exceedingly important attributes for a commercially viable polymerization catalyst.
