(57) [Summary] According to the present invention, a lactic acid-based polymer containing 0.001 to 5 parts by weight of at least one additive selected from an ultraviolet absorber and a light stabilizer, based on 100 parts by weight of a lactic acid-based polymer. A polymer composition is provided. [Effect] The lactic acid-based polymer composition of the present invention gives a molded article having excellent weather resistance. In addition, since the lactic acid-based polymer composition of the present invention maintains the original hydrolyzability of the lactic acid-based polymer, the molded product obtained from the composition has a natural environment when it is discarded after use. It will not decompose and will not accumulate as waste. |
