제목 Catalytic CO2/prolylene oxide copolymerization
초록 Double metal cyanide complex (DMC) prepared by salt metathesis reaction of K3Co(CN)6 with ZnCl2 is commercially used in propylene oxide (PO) homopolymerization, which also shows activity in PO/CO2 copolymerization though CO2 insertion is not full; fraction of carbonate linkage to ether linkage (FCO2) fluctuates in a wide range (10-60 mol%) depending on the preparation method and conditions. Preparation of the DMC catalyst is somewhat tedious, requiring many times uneasy washing process. In this work, we disclose a preparative scale (100 g scale) synthesis of H3Co(CN)6 of which structure was elucidated by X-ray crystallography. The DMC catalyst prepared with H3Co(CN)6 ​yielded polymers with high carbonate linkage fraction (FCO2 0.48-0.66, depending on CO2 pressure).
