Abstract: A finely powdered polyamide resin is manufactured by a method which comprises dissolving a polyamide resin in a water-containing isopropyl alcohol under increased pressure at temperatures of 150.degree. to 155.degree. C. and subjecting the resultant solution to vigorous agitation while cooling for thereby educing therein finely divided polyamide resin particles of diameters of the order of microns.
