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, an aqueous acrylic acid solution and acrylamide 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 dyeability-improving agent comprising the salt of the copolymer and containing 3% of acrylamide as a third component was obtained.
