PROBLEM TO BE SOLVED: To provide a method for coagulating resin particles that is capable of redispersing easily the resin particles after coagulation. SOLUTION: The coagulating method for hydrophobic resin particles comprises adding the resin particles in a dispersing liquid with a water-soluble polymer having hydrophobic groups at both terminals of the molecule in a concentration of the water-soluble polymer of 0.3-1.6 wt.% in the aqueous dispersion of the hydrophobic polymer particles. The redispersing method for redispersing the coagulated spherical resin particles comprises controlling the concentration of the water-soluble polymer having hydrophobic groups at both terminals of the molecule outside the above-described concentration range in the mixture containing the coagulated hydrophobic resin particles obtained by the coagulating method. |
