PROBLEM TO BE SOLVED: To provide a polymer having realized an ultimately improved superior impact resistance and a low haze.SOLUTION: In the biodegradable polymer composition of the present invention having an improved impact resistance, an impact resistance enhancer having large particle diameters is dispersed within a continuous phase of a biodegradable polymer. This impact resistance enhancer has a core-shell structure, and its average particle diameter exceeds 250 nm. This composition having an improved impact resistance exhibits a favorable impact-resistant characteristic and a low haze. The biodegradable polymer is preferably polylactic acid or polyhydroxybutyric acid. This composition includes 30-99.9 wt.% of the biodegradable polymer and 0.1-15 wt.% of at least one type of impact resistance enhancer. |
