Sodium styrene sulfonate is one of the most suitable monomers for synthesizing water-soluble polymer materials, and its polymer can be used as dyeing modifier; The polymer coordination compound formed by sodium styrene sulfonate and polyvinyl benzyl trimethyl ammonium chloride can be used as artificial physiological membrane, etc The aqueous solution polymer prepared from this product can be used as flocculant, cosmetic dispersant and hair styling agent. This homopolymer or copolymer is an excellent antistatic agent for plastics, fibers, paper, etc. In addition, it is used as ion exchange resin and exchange membrane; It is also used for photosensitive chemicals (gelatin viscosity regulator) microcapsules, electroplating electrophotographic developers and medicines for treating ulcers.
