PROBLEM TO BE SOLVED: To provide an extrusion molded product of polylactic acid which is excellent in heat resistance and the like.SOLUTION: An extrusion molded product comprises a polylactic acid resin (A component) having an amide bond obtained by reacting at least polylactic acid units having L-lactic acid as a major component and polylactic acid units having a D-lactic acid as a major component with polyisocyanate. The weight average molecular weight of the polylactic acid units is in the range of 5000-70,000, and the proportion of carboxyl groups at a terminal functional group of each polylactic unit exceeds 50%, while the weight average molecular weight of polylactic acid resin (A component) is 80,000-50,0000. |
