首次采用新型双酚盐钇醚催化剂合成了高全同立构（Pm= 0.97）和高分子量（~ 105 g/mol）的聚2-乙烯基吡啶。这些催化剂还显示出高活性和对低负载的耐受性。计算研究和动力学实验提供了一个基本的理解的引发，传播，和立体控制机制的钇催化剂介导的聚合反应。
Poly(2-vinylpyridine) with highly isotactic (Pm= 0.97) and high-molecular-weight (∼105g/mol) characteristics was obtained for the first time using novel yttrium bis(phenolate) ether catalysts. These catalysts also showed high activity and tolerance to low loadings. Computational studies and kinetic experiments provided a fundamental understanding of the initiation, propagation, and stereocontrol mechanism governing the polymerization reactions mediated by yttrium catalysts.
