| Abstract: | Water-borne emulsions of lightly sulfonaed polystyrene ionomer(SPS) were prepared by phase inversion technique.The mean particle size of emulsions was smaller than 200nm. Penetrative type PMMA/SPS hybrid microemulsions were prepared when another lyophilic monomer was initiated in the core of SPS emulsion particle.The effect of initial concentration, monomer contents and solvent polarity on the polymerization process and the stability of microemulsion were discussed.It was found that the rate of conversion was varied with the variation of initial concentration. |
