| introduction | 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 film, etc. The aqueous polymer made from this product can be used as flocculant, cosmetic dispersant and hair styling agent; this product homopolymer or copolymer is an excellent antistatic agent such as plastic, fiber, paper, etc. In addition, it is used as ion exchange resin and exchange membrane. It is also used in micro capsules of photosensitive chemicals (gelatin viscosity regulator), electroplated electronic photography developer and drugs for treating ulcer. |
| properties | white to yellowish crystalline powder. Relative molecular mass 206.19. Relative density 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 ℃). This product has vinyl, coupled with the induction effect of para-sulfonic acid group, it has strong reactivity and polymerization ability, so it can be used as a vinyl monomer with sulfonic acid group. Male mice LD5016000mg orally/kg. |
| use | sodium p-styrene sulfonate is a surfactant with a wide range of uses, used in the manufacture of acrylic fiber (DuPont process); The copolymer or copolymer mixture of this product and acrylic acid (copolymer and acrylic acid blend) can be used as a dyeing modifier to improve the dyeing performance of basic dyes; Used as a reactive emulsifier, it has better stability and water resistance; The polymer coordination compound formed by this product and polyvinyl benzyltrimethylammonium chloride can be used as artificial physiological membranes (such as artificial kidneys, contact lenses, etc.), industrial dialysis membranes, battery separators, rectifiers, etc.; The water-soluble polymer made of this product can be used as flocculant, cosmetic dispersant, hair styling agent; Homopolymer or copolymer of this product, it can be used as an antistatic agent for plastics, fibers, paper, etc.; This product can be made into ion exchange resin or ion exchange membrane; This product can also be used for photosensitive chemicals (adjusting the viscosity of gelatin), Microcapsules, electronic photography developer, electroplating bath additives (to improve gloss), medicine, etc. used to prepare polypropylene fiber, acrylic fiber dyeing modifier, reactive emulsifier, nylon, recording paper, polyester and other charging preventive agent, sulfur exchange resin, etc. Dyeing improvers (propylene fiber, polyester, polypropylene fiber, rayon), reactive emulsifier, polysulfur misbody (dialysis membrane, battery, artificial body membrane), charge prevention Agent (nylon, record paper, polyester), sulfur exchange resin (membrane), photo agent (micro membrane), electroplating gloss agent The third monomer mainly used in the dry production of acrylic fiber |
| production method | 1. 98% concentrated sulfuric acid is used as sulfonating agent, Ag2SO4 is used as catalyst and hydroquinone is used as polymerization inhibitor. Concentrated sulfuric acid: styrene (molar ratio) = 2: 1, catalyst mass fraction 1%, polymerization inhibitor mass fraction 1%. When the temperature is 54 ℃, the material is added, the temperature is increased to 70 ℃, the temperature is reacted at a constant temperature for 2~2.5h to obtain a brown solution, and then sodium hydroxide is used to neutralize to obtain sodium styrene sulfonate monomer, and the polymerization monomer can be reached by crystallization. The reaction formula is as follows: |
