Poly(sodium-p-styrenesulfonate) is widely used as a dispersant in various industrial applications, particularly in water treatment processes where it helps to stabilize and prevent the aggregation of suspended particles. In the field of coatings and paints, it acts as a stabilizer for pigments and fillers, ensuring even distribution and improved product quality. It is also employed in the production of specialty polymers and resins, where it enhances the mechanical properties and stability of the final materials. Additionally, this chemical finds use in the formulation of personal care products, such as shampoos and conditioners, to improve texture and viscosity. In the pharmaceutical industry, it serves as an excipient in drug formulations, aiding in the controlled release of active ingredients. Its ability to bind with positively charged molecules makes it valuable in biochemical research for applications like protein purification and DNA extraction.
