Abstract
The present invention relates to a method of manufacturing polyalkylene carbonate. More specifically, the method of manufacturing polyalkylene carbonate includes solution-polymerizing an epoxide compound and carbon dioxide in the presence of a cobalt complex having a neutral singe-site as a catalyst and a solvent, thereby providing stability and adjusting degree of polymerization and being advantageous for performing a post-treatment process after polymerization.
