Chemical Properties:Sodium p-styrenesulfonate (NaSS) is a functional monomer having a radical polymerizable vinyl group, a hydrophobic benzene ring having π electrons, and a sulfonic acid (salt) group that is a strong electrolyte and has been valued in various industrial fields.With the inductive effect of sulfo radical on the para position against vinyl group, sodium p-styrenesulfonate (NaSS) possesses the highest reactivity (polymerization activity) among all sulfonated vinyl monomers. It performs radical polymerization in such polar solvents as DMF, DMSO and water using common or redox polymerization initiators. For example, it has been used as a reactive emulsifier in order to improve stability of an emulsion and water resistance or cationic dye dyeability of a (emulsion) polymer.
