Poly(sodium-p-styrenesulfonate) Chemical Properties,Uses,Production

Chemical Properties

white to tan powder

Uses

Scale inhibitor and dispersant for metal salts and oxides.Anionic polyelectrolyte.

Uses

Dispersant for calcium carbonate and metal oxides, suspending aid for particulates and scale control agent for water treatment.

Uses

Effective antistatic and specialty dispersant.

Uses

Dispersant for metal oxides and sulfates, suspending agent for particulates, protective colloid for oil-in-water emulsions and viscosity modifier in aqueous-based adhesives.

Uses

sodium polystyrene sulfonate is a film former. It holds the actives on site and gives the feeling of skin tightening. It is synthetically manufactured.

Definition

ChEBI: A polymer composed of repeating sodium 4-ethylbenzenesulfonate units.

Safety Profile

Mildly toxic by ingestion. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of SOx and Na2O. See also SULFONATES.

Purification Methods

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. [Kowblansky & Ander J Phys Chem 80 297 1976.]
