| 摘 要： | Copolymerization of propylene oxide(PO)/carbon dioxide(CO2) and lactide(LA) is achievable to form new copolymers, combining the advantages of both poly(propylene carbonate)(PPC) and polylactide(PLA). In this study, we designed a dinuclear Salen-Cr(Ⅲ) complex, which showed higher efficiency for copolymerization of PO/CO2 and LA than that of mononuclear Salen-Cr(Ⅲ) complex. Besides, we successfully obtained gradient and random copolymers of PPC-PLA in one pot. Furthermore, by...
