Polystyrene sulfonic acid, the acid whose salts are the polystyrene sulfonates, has the idealized formula (CH 2 CHC 6 H 4 SO 3 H) n. The material is prepared by sulfonation of polystyrene: (CH 2 CHC 6 H 5) n + n SO 3 → (CH 2 CHC 6 H 4 SO 3 H) n. Several methods exist for this conversion, which can lead to varying degree of sulfonation.
Potassium binders are medications that bind potassium ions in the gastrointestinal tract, thereby preventing its intestinal absorption. This category formerly consisted solely of polystyrene sulfonate, a polyanionic resin attached to a cation, administered either orally or by retention enema to patients who are at risk of developing hyperkalaemia (abnormal high serum potassium levels).
These methods include polystyrene microspheres, nanoparticles, and solid foams. In the biomedical engineering field, these methods assist researchers in drug delivery, diagnostics, and imaging strategies. [1] [2] A common group of medication that utilizes a combination of polystyrene and sulfonate functional groups are polystyrene sulfonates. [3]

Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / is a synthetic polymer made from monomers of the aromatic hydrocarbon ...
Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a composite material where PEDOT (the conductive polymer) provides electrical conductivity, and PSS (polystyrene sulfonate) acts as a counter-ion to balance the charge and improve the water solubility and processability of PEDOT.
It is widely used in place of polystyrene owing to its greater thermal resistance. The chains of between 70 and 80% by weight styrene and 20 to 30% acrylonitrile. [ 1 ] Larger acrylonitrile content improves mechanical properties and chemical resistance, but also adds a yellow tint to the normally transparent plastic.
Polysulfone (PSU) repeating unit. Polyethersulfone (PES) repeating unit. Polysulfones are a family of high performance thermoplastics.These polymers are known for their toughness and stability at high temperatures.
