The present invention relates to the use of group 3 post-metallocene complexes based on sterically encumbered bis(naphthoxy)pyridine and bis(naphthoxy)thiophene ligands in the ring-opening polymerisation of polar monomers such as, for examples, lactones, lactides, cyclic carbonates.
本发明涉及使用基于空间位阻双(
萘氧基)
吡啶和双(
萘氧基)
噻吩配体的三族后
金属配合物在极性单体的开环聚合中的应用,例如内酯,内酰胺和环状
碳酸酯。
