Poly(styrenesulfonic acid), sodium salt [MW ~ 4,600]

Poly(styrenesulfonic acid) (PSSA) is a highly acidic, water-soluble polymer containing sulfonic acid functional groups. These groups impart strong ionic conductivity and hydrophilicity, making PSSA valuable in proton exchange membranes, polyelectrolytes, and ion-exchange resins. PSSA is widely used in fuel cells, coatings, and biomedical applications due to its strong acidic nature and high solubility in water.
