    摘要： The present disclosure relates to a multilayer film including polyalkylene carbonate, and more particularly to a multilayer film including a core layer prepared by blending polyalkylene carbonate and an ethylene vinyl acetate copolymer in a predetermined ratio, and an outer layer of polyolefin. The multilayer film does not have delamination behavior because two layers are adhered each other with a simple process without an additional step for introducing an oxygen-barrier layer even without adhesive or tie layers, and has an excellent oxygen barrier property. In addition, since an additional process for imparting barrier properties and a separate adhesive or tie layer are not required in the manufacturing method, the cost can be reduced and the layer structure can be simplified, which may greatly reduce the manufacturing cost.

    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.

    摘要： The present invention relates to an organic zinc catalyst suppressing agglomeration among catalyst particles during a manufacturing method to have more uniform and finer particle size, thereby showing a more improved activity in a polymerization process for manufacturing a polyalkylene carbonate resin, a manufacturing method thereof, and a manufacturing method of a polyalkylene carbonate resin using the same, wherein
    the organic zinc catalyst is a zinc dicarboxylate-based organic zinc catalyst used for a reaction in which a polyalkylene carbonate resin is manufactured from carbon dioxide and epoxide and includes a monocarboxylic acid-derived moiety having a C3-C15 aliphatic hydrocarbon group (provided that at least one oxygen or carbonyl group is included or not included in the aliphatic hydrocarbon group) that is bonded to an end of at least one side of the zinc dicarboxylate-based organic zinc catalyst.
