A novel SalenCo III (2,4‐dinitrophenoxy) (Salen = N,N' ‐bis(3,5‐di‐ tert ‐butylsalicylidene)‐1,2‐cyclohexanediamino) and 1,10‐phenanthroline monohydrate catalyst system was designed and employed for the copolymerization of CO 2 and propylene oxide (PO). The perfectly alternating copolymerization of CO 2 and PO proceeds effectively under middle temperature and pressure to yield poly(propylene carbonate) with a high yield and a high number average molecular weight of polymer. The structure of polymer was characterized by the IR and NMR measurements. The perfectly alternating copolymer was confirmed. The MALDI‐TOF spectrum insinuates that the copolymerization of CO 2 and PO was initiated by H 2 O. Copyright © 2016 John Wiley & Sons, Ltd.
