- HIGH-PURITY SODIUM P-STYRENESULFONATE WITH EXCELLENT HUE, METHOD FOR PRODUCING THE SAME, POLY (SODIUM P-STYRENESULFONATE) WITH EXCELLENT HUE USING THE SAME, AND DISPERSANT AND SYNTHETIC STARCH FOR CLOTHING FINISHING USING THE POLY ( SODIUM P-STYRENESULFONATE)
-
Provided are high purity sodium p-styrenesulfonate with an excellent hue which is useful as a reactive emulsifier or dispersant for producing a polymer emulsion, or synthetic starch for clothing ironing and poly(sodium p-styrene-sulfonate) with an excellent hue using the same or sodium p-styrenesulfonate improved in fluidity while keeping good solubility. An aqueous p-β-bromoethylbenzenesulfonic acid solution and an aqueous sodium hydroxide solution are reacted under specific conditions to control the particle size, thereby obtaining sodium p-styrenesulfonate particles improved in a balance between fluidity and solubility, and further, impurities such as isomers are reduced, thereby obtaining high-purity sodium p-styrenesulfonate with an excellent hue.
