Abstract
The process of the present invention for producing polymer particles with an irregular shape by polymerizing a water-soluble polymerizable monomer in a system comprising a hydrophobic organic solvent inert to the polymerization and an aqueous solution of the water-soluble polymerizable monomer is characterized in that the system a glycoside compound having such a structure that the hydrogen atom of the hemiacetal bond in the compound has been substituted for a hydrophobic group, or a gluconamide compound as a dispersant.
