The present invention relates to a process for producing a polyalkalene carbonate resin. More specifically, after the polymerization of the polyalkylene carbonate, by-products are removed with a large amount of water to purify the reaction mixture, and further, a catalyst purification process using a filter is performed in the process of removing the catalyst residue, Is less than 1% by weight, it is possible to provide a process for producing a polyalkylene carbonate resin which can prevent the decomposition of the polymer and improve the physical properties and quality of the final resin product. |
