Alternating Copolymerization of Carbon Dioxide and Cyclohexene Oxide and Their Terpolymerization with Lactide Catalyzed by Zinc Complexes of N,N Ligands
For the alternatingcopolymerization of CO2 and cyclohexeneoxide, a variety of zinc acetate complexes with new aminoimidoacrylate ligands has been synthesized and tested as catalysts. All complexescatalyzed the reaction and structure-activity investigations revealed that the highest activities and selectivities were reached when the ligand’s aromatic rings were 2,6-substituted by alkyl groups of
