Polylactic acid block copolymer |
abstract |
A polylactic acid block copolymer composed of a poly-L-lactic acid segment containing L-lactic acid as a main component and a poly-D-lactic acid segment containing D-lactic acid as a main component and satisfying the following formulas (1) and (2) . Sc = ΔHh / (ΔHl + ΔHh) × 100> 80 (1) 1 <(Tm−Tms) / (Tme−Tm) <1.8 (2) INDUSTRIAL APPLICABILITY The present invention can provide a polylactic acid block copolymer that is excellent in transparency, heat resistance, and mechanical properties and forms a polylactic acid stereocomplex. |
