Abstract	Abstract The copolymerizations of carbon dioxide (CO 2 ) and cyclohexene oxide (CHO) using nano-sized double and multi-metal cyanide catalysts were investigated. The nano-sized double metal cyanide (NDMC) catalyst was prepared by reacting K 3 [Co(CN) 6 ] 2 and ZnCl 2 in a reverse emulsion condition and nano-sized multi-metal cyanide (NMMC) catalyst by reacting K 3 [Co(CN) 6 ] 2 , K 4 Fe(CN) 6 , YCl 3 and ZnCl 2 at the similar conditions. Neutral surfactant, Igepal CA-520, used in the preparation step played important roles in acting both as an emulsifier and as a complexing reagent. NDMC and NMMC catalysts were demonstrated to be highly effective for copolymerizations of CHO with CO 2 . The catalysts showed catalytic activity as high as 41.6 g/mol of Zn per hour at 80 °C and the carbonate content in the copolymer was estimated to be 57.8%. Effects of reaction conditions such as reaction time, temperature, CO 2 pressure and catalyst concentration on copolymerizations were investigated.
