Copolymerization of Propylene Oxide and Carbon Oxide Catalyzed by Nano SalenCoCl Complex

In this investigation, nanoSchiff bases Cobaltic complex was synthesized and used as the initiator in the copolymerization of carbon oxide and propylene oxide (PO). The nanoCobaltic complex was characterized by infrared spectroscopy (IR), and nuclear magnetic resonance spectroscopy (NMR). The influences of different factors, including reaction time, reaction temperature, and pressure of CO2 on the synthesis of polycarbonate were described. The results show that nanoCobaltic complex could be successfully applied in the copolymerization of CO2 and PO. The optimum conditions of the polymerization, which include CO2 pressure of 30 bar, reaction temperature of 80 °C, and reaction time of 3 hours.
