Abstract: Double metal cyanide complex (DMC) based on Zn3[Co(CN)6]2 was prepared and employed as catalyst for the copolymerization of propylene oxide and carbon dioxide.Effects of reaction conditions on catalytic performance and the compositions of products were investigated.The results show that these catalysts demonstrate highly catalytic activity over 2 000 g copolymer per gram of Zn3[Co(CN)6]2.The copolymers prepared were characterized by FT-IR,1H NMR,and the molar fraction of CO2 for copolymer (FCO2) was as high as 0.3 under optimum condition,coupling product of propylene carbonate was also identified as co-product.It is also found that lower temperature and high reaction pressure are favorable for incorporation of CO2 into copolymer.

Key words: double metal cyanide complex, propylene oxide, carbon dioxide, copolymerization
