Poly(sodium 4-styrenesulfonate) (PSS ,Poly(styrene sulfonic acid) sodium salt) is an organic compound, light amber liquid, odorless, and easily soluble in water. Sodium polystyrene sulfonate solution is a water-soluble polymer with a unique effect, used in reactive emulsifiers, water-soluble polymers (coagulants, dispersants, container cleaning agents, cosmetics, etc.), water treatment agents (dispersion Chemicals, flocculants), sulfur exchange resins (membrane), photographic agents (membrane), semiconductors, imaging films, heat conduction products, etc.
Poly(sodium 4-styrenesulfonate) is used as Polyelectrolyte. It is also used as electroconductive and antistatic resin for electrographic and electrophotographic substrates.
Poly(sodium 4-styrenesulfonate) is used to prepare adsorption ultrafiltration membranes and is used to treat heavy metal water pollution. Sodium polystyrene sulfonate (PSS) has strong hydrophilic properties. When gelling in water, it will migrate to the surface of the particles and then be mainly fixed on the surface of the particles or the surface of the pore channels. The adsorption ultrafiltration membrane prepared based on it not only can remove water Macromolecules, colloids and other substances, and can simultaneously remove various toxic and harmful cations in the water.
Poly(sodium 4-styrenesulfonate) is a film former. It holds the actives on site and gives the feeling of skin tightening. It is synthetically manufactured.
Poly(sodium 4-styrenesulfonate) used as an anionic polyelectrolyte, suspending aid for particulates and scale control agent for water treatment. It is an effective antistatic and specialty dispersant, protective colloid for oil-in-water emulsions and viscosity modifier in aqueous-based adhesives.
ChEBI: A polymer composed of repeating sodium 4-ethylbenzenesulfonate units.
Poly (sodium 4-styrenesulfonate) (PSS) a cation exchange polyelectrolyte. PSS may be used to produce mechanically stable and very reproducible coatings.
Poly(sodium 4-styrenesulfonate), also named as polystyrene sulfonate, is a water-soluble polymer. It has sulfonate groups and mostly used as ion-exchange resins to remove ions such as potassium, calcium, sodium from solutions in biomedical applications. PSS is commonly used as potassium ions binder to cure chronic and acute kidney disease in people suffering hyperkalemia.30 PSS may have side effects when it is blended with sorbitol, causing intestinal necrosis[1].
Mildly toxic by ingestion. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of SOx and Na2O. See also SULFONATES.
Purify the polymer by repeated precipitation of the sodium salt from an aqueous solution by MeOH, with subsequent conversion to the free acid by passage through an Amberlite IR-120 ion-exchange resin. [Kotin & Nagasawa J Am Chem Soc 83 1026 1961.] Recrystallise it from EtOH. Alternatively purify it by passage through cation and anion exchange resins in series (Rexyn 101 cation exchange resin and Rexyn 203 anion exchange resin), then titrated it with NaOH to pH 7. The sodium form of polystyrenesulfonic acid is precipitated by addition of 2-propanol. Dry it in a vacuum oven at 80o for 24hours, and finally increasing to 120o before to use.
