We have prepared a series of double metal cyanide (DMC) catalysts, with various crystal architectures. The resultant heterogeneous catalysts exhibited high efficacy for the ring-opening (co)polymerization of various cyclic monomers including of epoxides and lactones (Fig. 1). Kinetic and mechanistic studies provided us with insight into the DMC-catalyzed ROP of the aforementioned monomers. The pure monoclinic DMC compound is a highly stable and reusable catalyst
