PROBLEM TO BE SOLVED: To provide a multi-block copolymer that can achieve both a high heat resistance and elastic modulus and a high elongation at break.SOLUTION: Provided is a stereocomplex multi-block copolymer including a block composed of polylactic acid and a block composed of polycaprolactone, and in which the block composed of polylactic acid is stereo-complexed by a chiral polymer composed of a chiral monomer having an enantiomeric relationship with a lactic acid constituting the polylactic acid.SELECTED DRAWING: None |
