Copolymerization of propylene oxide and carbon dioxide was successfully carried out by using double metal cyanide complex (DMC) based on Zn 3[Co(CN) 6] 2. It has been found that this catalyst demonstrated highly enhanced catalytic activity over 1000 g copolymer per gram of Zn 3[Co(CN) 6] 2 compared...
