The production of polyamide 1010 polymer particles, in which polyamide 1010 resin, a different polymer B and an organic solvent are dissolved and mixed and thereupon an emulsion is formed within a system for phase separation into two phases, being a solution phase having the polyamide 1010 resin as the main component and a solution phase having the polymer B as the main component, and thereafter a poor solvent of the polyamide 1010 resin is brought into contact therewith to precipitate the polyamide 1010 resin, wherein the formation of the emulsion is carried out at a temperature of 100°C or higher, thereby making it possible to obtain highly crystalline polyamide 1010 particles having a high sphericity. |
