発明の名称 (英語) METHOD FOR PRODUCING STEREO COMPLEX CRYSTALS OF POLYLACTIC ACID, POLYLACTIC ACID, AND MOLDED BODY, SYNTHETIC FIBER, POROUS BODY AND ION CONDUCTOR COMPRISING SAME
発明の概要(英語) Disclosed are: a method for producing stereo complex crystals of polylactic acid whereby polylactic acid having excellent heat resistance and containing stereo complex crystals at a high ratio can be efficiently produced; the thus obtained polylactic acid that contains stereo complex crystals at a high ratio and has excellent heat resistance; and a molded body, a synthetic fiber, a porous body and an ion conductor each having excellent heat resistance. Specifically disclosed is a method for producing stereo complex crystals of polylactic acid, comprising: a step for dissolving in a solvent a block copolymer, which comprises polylactic acid containing an L-lactic acid unit or polylactic acid containing a D-lactic acid unit together with at least one kind of an organic polymer having a different structure from polylactic acid, and a polylactic acid homopolymer containing a D-lactic acid unit or a polylactic acid homopolymer containing an L-lactic acid unit, said lactic acid unit being an optical isomer that is not contained in the aforesaid block copolymer, to give a polymer mixture solution; and a step for removing the solvent from the polymer mixture solution.
