Polyimide powder and method for producing the same

摘要

A polyimide powder which can provide a molding having excellent both strength and heat resistance by heat-press molding, and a method for producing such polyimide powder are disclosed. The polyimide powder comprises spherical polyimide particles having a particle size distribution of from 0.5 to 20 mu m and a mean particle diameter of from 1 to 15 mu m, and comprising a repeating unit represented by the formula <IMAGE> wherein Ar represents an aromatic diamine residue.
