Catalyst Systems Based on Phenolate Complexes for Immortal Ring-Opening Polymerization of Cyclic Esters and Carbohydrates |
摘要 |
A method can include immortal ring-opening homopolymerisation of cyclic carbonates or cyclic esters in the presence of a catalytic system, or sequential two-step ring-opening block copolymerisation of one or more cyclic monomers selected from cyclic carbonates or cyclic esters in the presence of the catalytic system. The catalytic system can include a phenolate supported metallic complex. The catalytic system can also include an alcohol or a primary amine containing aliphatic and/or aromatic moieties. The alcohol or primary amine can be present in a molar ratio with respect to the metallic complex that is larger than 1. |
