Abstract

In previous work, our group found that tetradentate phenol ether rare earth catalysts show highly isoselectivity for 2-vinylpyridine polymerization. In order to explore the influence of ether chain on 2-vinylpyridine polymerization, six rare earth complexes with bidentate phenol ester ligands with similar structures were synthesized. Polymerizations of 2-VP were also explored, the effects of metal centers and different kinds of ligands on the polymerization were also discussed.
