| Abstract: | Synthesis of the title polymer (PPCS) was accomplished by terpolymerization of CO_2, propylene oxide (PO), and succinic anhydride (SA). It was found that in the molecular chains, the carbonate and the succinic units were arranged randomly; the molecular weight of the copolymer can be adjusted up to 3×10~4; PPCS can be degraded by Phanerochaete Chrysosporium. Weight loss and decrease of molecular weights were observed when PPCS was hydrolyzed. |
