摘要：Poly(2-vinylpyridine) with highly isotactic (P-m = 0.97) and high-molecular-weight (similar to 10(5) g/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.
