Two new kinds of active nanolamellar double metal cyanide complex (DMC) catalysts, Zn–Ni DMC and Co–Ni DMC catalysts, were successfully synthesized by ball milling, which is a clean, green, convenient and rapid synthetic method. Their structures were characterized by FTIR spectrometer, elemental analysis, and SEM images. The results showed that both Zn–Ni DMC and Co–Ni DMC were nanoscale, which improved the catalytic activity by improving its surface area and ensured a better exposure of active sites to the reactants. The alternating copolymerization of CO2 and propylene oxide with the two catalysts showed high catalytic activity, and after 24 h at 4 MPa and 60 °C yielded poly(propylene carbonate) (PPC). The PPC from catalysis Zn–Ni DMC has molecular weight (Mn) up to 10,344 g/mol and polydispersity (PDI) of 1.45 with 83.5% carbonate linkages, while from catalysis Co–Ni DMC has molecular weight (Mn: 8478 g/mol) and PDI of 1.44 with 73.7% carbonate linkages. FT-IR and 1H NMR confirmed product formation.
