Abstract of the Disclosure The present invention provides novel spherical grains of poly(.alpha.-amino acid) which can be used as a filler in chromatography, cosmetic powder and the like. The spheri- cal grains can be produced by a method which comprises the steps of preparing a solution of hydrophobic poly(?-amino acid) such as poly n-leucine dissolved in an organic solvent; adding the solution to an aqueous medium and agitating the medium so as to obtain a dispersion of the spherical grains of the poly(.alpha.-amino acid) dispersed in the aqueous medium while evaporating the organic solvent; and taking out the spherical grains of polyamino acid from the dispersion.
