The low cost and low toxicity of carbon dioxide (CO2) make it an attractive industrial raw material. Consequently, the methods for using CO2 as a practical carbon feedstock are being aggressively investigated. One of the most intensely studied areas involves the use of CO2 for the synthesis of polymers. Double metal cyanide (DMC) compounds, Zn3[Co(CN)6]2xH2O, can be categorized as Prussian blue analogues and are the reaction products of a water-soluble metal salt and a water soluble metal cyanide salt. They are well known catalyst not only for the polymerization of epoxides, but also for the copolymerization of CO2 and epoxides. In this study, a new type of DMC catalyst using novel complexing agent is investigated and used for synthesis of copolymerization of CO2 and epoxides. Resultant terpolymers were characterized by gel permeation chromatography, universal testing machine, thermogravimetric analysis, differential scanning calorimetry and various spectroscopic techniques. |
