使用新的亚氨烯醇合钛络合物，乙烯以前所未有的活性方式聚合，同时提供具有高分子量（Mn > 10（5）g mol-1）和极窄分布（Mw/Mn 1.01）的聚合物;即使在75 ℃的高温下也保持活性特征，并且可获得嵌段共聚物。
With a new titanium imineenolato complex, ethylene is polymerized in an unprecedented living fashion affording a polymer with a high molecular weight (Mn > 10(5) g mol-1) and an extremely narrow distribution (Mw/Mn 1.01) at the same time; the living character is also retained even at an elevated temperature of 75 degrees C, and blockcopolymers are accessible.
