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.
Polystyrene integrated solid foams are not commonly used in biomedical applications but have shown promise as a new drug delivery vehicle. The manipulation of the porous foam networks is a fundamental component in solid foam dosing – affecting variables such as dissolution, adsorption, and drug diffusion. [4]
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).
Acids are classified as either weak or strong (and bases similarly may be either weak or strong).Similarly, polyelectrolytes can be divided into "weak" and "strong" types. A "strong" polyelectrolyte dissociates completely in solution for most reasonable pH values.
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.
Polystyrene may refer to: Polystyrene, a synthetic material (eg: Styrofoam) Polystyrene sulfonate, group of medications that treat blood potassium levels; Poly Styrene (1957–2011), the stage-name of Marianne Elliott-Said, a Somali-British punk musician
Polymerization is usually conducted in the presence of polystyrene sulfonate (PSS), which acts as a template. PSS also provides a counter ion, which balances the charges in the reaction and hinders the formation of by-products such as 3,4-ethylenedioxy-2(5H)-thiophenone, and keeps the PEDOT monomers dispersed in water or aqueous solutions .
