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.

当SPG膜孔径大于1.0 μm左右时，可得到单分散的含TDC单体乳液；而当孔径小于1.0 μm左右时，水分子更容易扩散并溶解到油水界面甚至油相内部与TDC生成对苯二甲酸，TPA积累到一定程度在油水界面上析出将膜孔堵塞，从而无法制得单分散乳液。
