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.

A reactive surfactant composition comprising one or more kinds of reactive surfactants is disclosed that may be used as an emulsifier for emulsion polymerization, a dispersant for suspension polymerization, a nonaqueous dispersant, or a resin modifier.
Solutions of an hydroxylamine or an at least partially neutralized hydroxylamine salt are stabilized against decomposition by adding thereto a thiosulfate, mercaptobenzothiazole, a mercaptothiazoline, a thiuram disulfide, thiourea or a mercaptoalkanol.
