Notes:
Sulfonated polystyrene (S-PS), which is of considerable scientific and technological interest, has been traditionally prepared by the sulfonation of preformed polystyrene. This report describes the preparation and properties of S-PS prepared by emulsion copolymerization of styrene and sodium styrene sulfonate. S-PS prepared by copolymerization gave solubility, solution behavior and thermal characteristics that are consistent with an ionomeric structure. The solubility characteristics indicated some chain-to-chain sulfonate heterogeneity. Thermal analysis studies indicated that the glass transition does not increase with increasing sulfonate content. This is contrary to what has been observed for S-PS prepared by sulfonation and suggests that the S-PS prepared by copolymerization is fundamentally different in structure than S-PS prepared by sulfonation of polystyrene.
