With increasing monomer concentration inside the disperse phase, the monodispersity of emulsions became slightly worse and the mean diameter of emulsions gradually became smaller. Monodisperse monomer-containing emulsions were obtained when the SPG membrane pore size was larger than 1.0 μm; however, when the SPG membrane pore size was smaller than 1.0 μm, no monodisperse emulsions were obtained because of the formation and chokage of p-phthalic acid crystals in the pores of the SPG membrane.
