Polyalkylene carbonate resin composition and method for preparing the same

Abstract

A polyalkylene carbonate resin composition having excellent thermal stability, and a method for preparing the same, and a polyalkylene carbonate resin composition including a polyalkylene carbonate and an organic acid, where the organic acid is included in an amount of 0.001 parts by weight to less than 0.5 parts by weight on the basis of 100 parts by weight of the polyalkylene carbonate, and a method for preparing the same. The polyethylene carbonate resin compositions exhibit molecular weight change ratios of 55% or less, and mass change ratios of 10% or less, and exhibit reduced decomposition by heat treatment.
