Synthesis of rare earth metal complexes based on phenol ether bidentate ligands and polymerization of 2-vinylpyridine

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-vinyl pyridine 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. (c) 2021 Elsevier Ltd. All rights reserved.

Rare earth catalysts with tetradentate phenol ether ligands exhibit high isoselectivity for 2-vinylpyridine polymerization, while the influence of ether chain and different types of ligands on the polymerization of 2-VP were also investigated.
