Highly active calcium chloride (CaCl₂) doped Zn-Co^Ⅲ double metal-cyanide (Ca-DMC) catalysts were firstly reported. Ca-DMCs presented a very higher polymer yield (> 54 kg polymer/g catalyst) at relative low temperature (80-115℃) toward ring-opening polymerization (ROP) of propylene oxide (PO) than did DMC catalysts without modification.
