    Abstract: Porous spherical particles of polyamide 11 or polyamide 12 can be produced by an industrially advantageous process which comprises the steps of mixing a polyamide solution of polyamide 11 or polyamide 12 dissolved in a phenol compound and a low molecular weight aliphatic alcohol which is a poor solvent for the polyamides but is well compatible with the phenol compound in the presence of a high molecular weight alkylene glycol to prepare a mixture solution having an initial viscosity of 10 mPa·s or more, and allowing the mixture solution to stand, to precipitate polyamide particles.
