CONTINUOUS PROCESS FOR MANUFACTURING ALIPHATIC POLYCARBONATE FROM CARBON DIOXIDE AND EPOXIDE COMPOUNDS

摘要

Disclosed is a continuous process for manufacturing aliphatic polycarbonate by polymerizing carbon dioxide and one or more epoxide compound in the presence of catalyst, in which carbon dioxide, one or more epoxide compound, and the catalyst are continuously supplied to polymerization reactor to produce aliphatic polycarbonate, separate unreacted carbon dioxide and epoxide compound and recycle them as raw materials.
