In this article, the lightly sulfonated poly(phenylene oxide) (SPPO) ionomers in a series of mixing solvents were emulsificated by water to form a series of water‐borne microemulsions. The phase inversion during the emulsification process of SPPO ionomer solutions was characterized by measuring the variation of conductivity, viscosity, and surface tension with the addition of water. The effects of properties of solvent systems on the phase inversion procedure, the particle size of emulsions with different solvent systems, and ionic contents of the polymer chain were discussed. © 2000 John Wiley & Sons, Inc.
