Beschreibung
Zusammenfassung:	The present invention relates to an organozinc-supported catalyst, a method for producing the same, and a method for preparing a polyalkylene carbonate resin using the catalyst. The organozinc-supported catalyst provided by the present invention includes a zinc dicarboxylate-based catalyst supported on a zinc compound layer formed on at least a portion of a support surface, and can be used repeatedly or continuously while exhibiting improved selectivity in the polymerization process for preparing a polyalkylene carbonate resin.
