Non-truly-spherical high-molecular fine particles are produced by a radical polymerization between a first radical-polymerizable monomer having a nucleophilic group and a second radical-polymerizable monomer having a group reacting with the nucleophilic group to form a covalent bond in a non-aqueous solvent in the presence of a dispersion-stabilizing resin.

Ring opening reactions of epoxides with oxygen nucleophiles catalyzed by a variety of quaternary onium salt, such as ammonium or phosphonium salt were explored. The results showed that tetrabutylphosphonium bromide (TBPB) among salts serves as the most efficient catalyst for this process and that expoxide ring opening reactions with a variety of oxygen nucleophiles including carboxyic acid and phenol
