METHOD FOR PREPARING POLYALKYLENE CARBONATE RESIN |
摘要 |
The present invention relates to a manufacturing method of a polyalkylene carbonate resin capable of suppressing agglomeration among catalyst particles during polymerization to maintain an excellent catalytic activity in a polymerization process, wherein the manufacturing method of a polyalkylene carbonate resin may include polymerizing epoxide and a monomer including carbon dioxide in the presence of a zinc dicarboxylate-based organic zinc catalyst and a dispersant, and the dispersant may include at least one selected from the group consisting of C1-C10 alkyl acrylate, C1-C10 alkyl methacrylate, C1-C20 monocarboxylic acid having an oxo group in a molecular structure, and a polyether-based polymer having C2-C6 alkylene oxide repeating units. |
