Abstract
The present disclosure provides a polyalkylene carbonate-based resin having excellent thermal stability, thereby having an improved heat shrinkage phenomenon, and a molded article produced using the same. The polyalkylene carbonate-based resin includes 100 parts by weight of a base resin including a polyalkylene carbonate resin and a polylactide resin, and 5 parts by weight to 10 parts by weight of a heat shrinkage prevention agent, wherein the base resin includes the polyalkylene carbonate resin and the polylactide resin in a weight ratio of 6:4 to 4:6, and the heat shrinkage prevention agent is one or more selected from the group consisting of a polyalkyl(meth)acrylate-based resin, a polyalphaolefin-vinyl acetate-based resin, and a polyoxyalkylene-based resin.
