い、ジオキサン、アルコールなどが好ましい。Next, when using a monomer or oligomer with high viscosity, it is preferable that the monomer contains a solvent. The reason for this is to lower the viscosity and make it easier to discharge from the pores, and to obtain a polymer with a smaller diameter since the volume decreases when the solvent is removed. The solvent is preferably dioxane, alcohol, etc., which have a high affinity for water.

濃度を一定の低い値に保つようにしてもよい。In the present invention, spherical particles can be obtained by utilizing the interfacial tension of monomers or oligomers. This is particularly effective when using epoxy monomers. Furthermore, if the monomer contains a solvent, it is necessary to remove the solvent in the receiving tank 30.
Industrially, it is most economical to use water for solvent removal. Therefore, it is most preferable to position the nozzle tip in the air and install a solvent removal tank containing water at the bottom. In this case, a water inlet 31 (FIG. 1) and an outlet 32 may be provided to maintain the solvent concentration at a constant low value.
