Abstract
The present invention relates to a polyhydroxyalkanoate (PHA) dispersion and a preparation method therefor. Specifically, according to one embodiment of the present invention, a method for preparing a PHA dispersion comprises a step of dispersing a PHA in a solvent by using particle dispersion, melt dispersion or solvent extraction, so that a PHA dispersion, which comprises PHA particles having an average diameter of 0.5-5 μm and a deviation of diameter of ±0.3 μm, can be prepared, and thus dispersibility, dispersion stability and processability can be improved.
