Organic zinc catalyst, preparation method thereof, and method of preparing poly(alkylene carbonate) resin using the same
An organic zinc catalyst having more uniform and fine particle size and showing more improved activity in a polymerization process for the preparation of a poly(alkylene carbonate) resin and a preparation method thereof, and a method of preparing a poly(alkylene carbonate) resin using the organic zinc catalyst, are provided. The preparation method of the organic zinc catalyst includes the steps of surface-treating a zinc precursor with a dispersant, and reacting the surface-treated zinc precursor with dicarboxylic acid to form a zinc dicarboxylate-based catalyst.
