Zinc and magnesium complexes supported by bulky multidentate amino-ether phenolate ligands: potent pre-catalysts for the immortalring-opening polymerisation of cyclic esters
A family of heteroleptic complexes of zinc and magnesium supported by bulky multidentate amino-ether phenolate ligands has been developed; in combination with external chain transfer agents, they constitute efficient binary catalytic systems for the immortalring-opening polymerisation of cyclicesters.
