Abstract
This disclosure relates to polyalkylene carbonate resin that inhibits decomposition of resin resulting from back-biting and the like when heat treated, and thus exhibits improved thermal stability, and a method for preparing the same. The polyalkylene carbonate resin may comprise a basic polyalkylene carbonate based repeat unit, a polyalkyleneglycol based repeat unit, and the polyalkylene carbonate repeat unit crosslinked by a specific compound.
