合成了一种以茚基和芴基为配体的新型立体刚性桥联茂锆催化剂，并研究了其作为乙烯/1-羟基-10-十一烯共聚催化剂的性能。使用MAO作为助催化剂的该催化剂促进聚合以制备具有高分子量（Mw：121000）和高极性单体含量（36.7摩尔%）的共聚物，在较高温度下显示较高的聚合活性。
New stereorigid bridged zirconocene having an indenyl group and a fluorenyl group as ligand was synthesized and investigated as an ethylene/1-hydroxy-10-undecene copolymerization catalyst. This catalyst using MAO as a cocatalyst promoted polymerization to produce copolymers having high molecular weight (Mw:121000) and high polar monomer content (36.7 mol%), displaying higher polymerization activities at higher temperature.
