Carbon dioxide-based copolymers with various architectures
关键字：Block copolymer，Carbon dioxide，Epoxide，Lactide/lactone，Cyclic anhydride，Junction
This review highlights recent advances in the synthesis of carbon dioxide (CO2)-based copolymers withboth linear (di-, tri-, and multi-block, etc.) and non-linear (star-block and grafting) architectures. Thecorresponding catalytic systems are summarized. The microstructure and polymerization mechanism ofvarious types of CO2-based copolymers, including block polycarbonates and block copolymers of p...
