Commercial grades of polyelectrolytes are available, includes - Poly diallyl dimethyl ammonium chloride (PolyDADMAC), Polyacrylic acid (PAA), Polystyrene sulfonate. We are mainly focus on PolyDADMAC and PAAs.
Polyelectrolytes have many applications, mostly related to modifying flow and improving the stability of aqueous colloids and gels or to induce agglomeration. For instance, they can be used to destabilize a colloidal suspension and to initiate flocculation and precipitation. They can also be used to impart a surface charge to neutral particles, enabling them to be dispersed in an aqueous solution. They are thus often used as thickeners, dispersant agents, conditioners, emulsifiers, ion-exchanger and clarifying agents. For example, they are used in water treatment as flocculation agents, in ceramic slurries as stablizing agents and in concrete mixtures as superplasticizers. Furthermore, many shampoos, soaps and cosmetics contain polyelectrolytes. Certain polyelectrolytes are also added to food products; for example, as food coatings and release agents. Examples are pectin (polygalacturonic acid), alginate (alginic acid), and carboxymethyl cellulose. All but the last are of natural origin.
Because polyelectrolytes are water-soluble, they are also used in biochemical and medical applications such as implant coatings and controlled drug release systems.
Large quantities of slightly cross-linked sodium polyacrylate-polyacrylamide copolymers, called hydrogels, are used as super absorbents (SAPs). The largest use of SAPs is found in baby diapers and other personal disposable hygiene products, such as adult protective underwear and sanitary napkins. The global super absorbent polymer market is expected to grow at a rate of 5.5% from 2014 to 2019 to reach a value of $ 8.56 billion.
