Polystyrene sulfonic acid Description

Polystyrene sulfonates are polymers derived from polystyrene but containing sulfonate functional groups. They are widely used to remove ions such as potassium, calcium and sodium from solutions in technical or medical applications.

Linear ionic polymers are generally water-soluble. Crosslinked materials (called resins) do not dissolve in water. These polymers are classified as polysalts and ionomers.

Under the name tolevamer, a polystyrene sulfonate was investigated by Genzyme as a toxin binding agent for the treatment of Clostridium difficile associated diarrhoea (CDAD), but never marketed.

Polystyrene sulfonic acid (PSS) CAS: 28210-41-5 could be used as water-soluble polymer, reactive emulsifier, water treatment agent.
