Abstract:
Provided is a method for preparing poly(alkylene carbonate) containing ether linkages, by the copolymerization of an epoxy compound and carbon dioxide, with a trivalent metal complex prepared from a salen type ligand containing a quaternary ammonium salt, and a double metal cyanide (DMC) catalyst together. The amount of ether linkages can be controlled by regulating the weight ratio of two catalysts and the carbon dioxide pressure.
