✦ Synopsis

Aqueous dispersions of lightly sulfonated polystyrene (SPS) that was neutralized by ammonia liquor were prepared. The variations of the conductivity and viscosity of SPS ionomer solution during the emulsification process and the effect of ionic contents on the phase inversion in the emulsification process were studied. The turning points in conductivity curve and the maximum viscosity were considered as the characters of phase inversion in the process of emulsification. The mechanism of phase inversion was inferred.

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
