(57) [Problem] To provide a method for producing acrylic polymer fine particles. SOLUTION: (1) a) In a medium containing water as a main component, A) having a solubility of 0.02% by mass or more in the medium at 20 ° C. and polymerizing the polymer using a monomer that is insoluble in the medium to obtain a polymer dispersion; A step of obtaining a coated polymer dispersion by dropping a monomer mixture into the polymer dispersion, and (2) a step of collecting polymer fine particles by spray-drying the polymer dispersion. A method for producing acrylic polymer fine particles comprising: |
