Uses and synthesis of Sodium p-styrenesulfonate powder

Sodium p-styrenesulfonate powder White to yellowish crystalline powder. Relative molecular mass 206.19. The relative density is 0.5(25℃). Melting point 330℃(decomposition). Insoluble in benzene, acetone, carbon tetrachloride, soluble in water (22.2 at 20℃), methanol (5.0 at 20℃), dimethylformamide (8.5 at 20℃). Sodium p-styrenesulfonate is one of the most suitable monomers for the synthesis of water-soluble polymers, which can be used as dyeing modifiers.

Sodium styrene sulfonate and polyvinyl benzyl trimethyl ammonium chloride form high molecular coordination compounds which can be used as artificial physiological membranes. Sodium p-styrenesulfonate powder can be used as flocculant, cosmetic dispersant and hair styling agent. Sodium p-styrenesulfonate homopolymers or copolymers are good antistatic agents for plastics, fibers and paper. In addition, it is used as ion exchange resin and exchange membrane; It is also used in microcapsules of photosensitive chemicals (gelatin viscosity regulator), electrophotographic developers for electroplating and medicines for treating ulcers.

Applications/Functions of Sodium p-styrenesulfonate powder

1. Sodium p-styrenesulfonate powder is used to prepare polypropylene fiber and acrylic fiber dyeing modifier, reactive emulsifier, nylon, record paper, polyester and other charging prevention agents, sulfur exchange resin
2. Sodium p-styrenesulfonate is mainly used as the third monomer in dry acrylic fiber production
3. Sodium p-styrenesulfonate and acrylic acid copolymer or copolymer mixture (copolymer and acrylic acid blend) can be used as dyeing modifier to improve the dyeing properties of basic dyes.

Physicochemical Property of Sodium p-styrenesulfonate powder

White to yellowish crystalline powder. Relative molecular mass 206.19. The relative density is 0.5(25℃). Melting point 330℃(decomposition). Insoluble in benzene, acetone, carbon tetrachloride, soluble in water (22.2 at 20℃), methanol (5.0 at 20℃), dimethylformamide (8.5 at 20℃). Sodium p-styrenesulfonate powder contains vinyl and has strong reactivity and polymerization ability due to its induction effect on the sulfonic acid group, so it can be used as vinyl monomer with sulfonic acid group.
