Patent ID: 8030382

Claim:
A composition comprising a polylactic acid (component A), a carbodiimide compound (component B) and a phosphoric acid ester metal salt (component C), wherein the component A is a mixture of a poly(L-lactic acid) and a poly(D-lactic acid), and wherein the composition has a stereo crystal rate (S) of 100% (the stereo crystal rate (S) is expressed by the following equation: S (%)=[Δ Hmsc /(Δ Hmh+ΔHmsc )]×100 ΔHmh is the crystal melting heat of a homo-phase crystal melting peak at a temperature lower than 190° C. observed in the DSC measurement and ΔHmsc is the crystal melting heat of a complex-phase crystal melting peak at a temperature of 190° C. or higher observed in the DSC. measurement).
