METHOD FOR MANUFACTURING POLYALKYLENE CARBONATE

摘要

The present invention relates to a method for manufacturing polyalkylene carbonate. Specifically, the method for manufacturing polyalkylene carbonate employs solution polymerization by means of a particular non-uniform catalyst and a solvent in a polymerization process of an epoxide compound and carbon dioxide so as to reduce side effect products, so that metal residue and by-product can be readily removed from the product, and heat control and process stability are improved by minimizing the risk caused by overheating of the reactants, thus readily providing a copolymer, and facilitating a scale-up of mass production.
