Beschreibung
Zusammenfassung:	The present invention relates to a polyimide powder and a preparation method therefor. With respect to the polyimide powder and the preparation method therefor, according to the present invention, a preparation process is simplified such that process efficiency can be improved, a polyimide is prepared in the form of a powder so as to facilitate molding thereof, and the polyimide has a low precipitation temperature and a high intrinsic viscosity so as to facilitate processing thereof, and has a uniform particle size so as to have excellent processability.
