Hydrogen Peroxide → Maleic acid, disodium salt

Participants

Reaction Steps

An aqueous sodium maleate solution was prepared by neutralizing maleic anhydride with an aqueous sodium hydroxide solution in a four-necked flask. The aqueous solution polymerization of this solution and an aqueous acrylic acid solution was effected in the presence of hydrogen peroxide and sodium hydroxide at 100° C. for 6 h. After neutralization with an aqueous sodium hydroxide solution, a dye-ability-improving agent comprising sodium salt of the copolymer was obtained.
