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]
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.
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 .
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.
A printer cartridge made of PPE and polystyrene; it is an example of a product which requires good dimensional stability and accuracy to fit.. PPE blends are used for structural parts, electronics, household and automotive items that depend on high heat resistance, dimensional stability and accuracy.
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
