摘要
A polylactic acid stereocomplex has a crystal melting peak temperature of 215° C. or more, wherein the crystal melting peak is a single peak and has a peak half width of 12° C. or less, and a crystal melting enthalpy of 60 J/g or more as measured by differential scanning calorimetry. The polylactic acid stereocomplex has a high melting point, good heat resistance, and a high level of mechanical properties and chemical resistance. The method for producing a polylactic acid stereocomplex includes chaotic mixing of 30 to 70 parts by weight of (A) poly-L-lactic acid and 30 to 70 parts by weight of (B) poly-D-lactic acid based on 100 parts by weight of the total of (A) poly-L-lactic acid and (B) poly-D-lactic acid.
