Sodium polystyrene sulfonate (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.
