METHOD OF PRODUCING POLYAMIDE RESIN FINE POWDER

摘要

PROBLEM TO BE SOLVED: To provide a method of producing high quality polyamide fine powder having high solubility in a solvent, excellent workability with improved dissolving speed in the solvent and improved efficiency of washing and drying by making a polyamide resin into fine powder. SOLUTION: This method of producing polyamide resin fine powder comprises the steps of adding a poor solvent of polyamide resin to a solution of polyamide resin in a solvent to form a slurry of dispersed polyamide resin, adding the slurry to a poor solvent of polyamide resin to convert to a state of dispersed fine powder and obtaining polyamide resin in the form of fine powder.
