Abstract:

The purpose of this study was to investigate the utilization of CO₂ in order to obtain polyether-polycarbonate by the co-polymerization of epoxide with CO₂ using microwave irradiation. Double metal cyanide containing Zn with Co, Fe(II), Fe(III) and Ni has been utilized as a catalyst for the co-polymerization reaction. The effect of microwave power, catalyst amount and types of catalysts has been studied. The microwaves were found to be successful in the synthesis of polyether-polycarbonate in a shorter reaction time with higher turnover numbers than those in conventional methods.
