HCID 6364608Maleic acid, disodium salt

Procedure

An aqueous solution of sodium maleate was prepared by neutralizing maleic anhydride with an aqueous sodium hydroxide solution in a four-necked flask. The aqueous solution polymerization of this product and acrylamide was effected in the presence of hydrogen peroxide at 100° C. for 6 h to obtain a dyeability-improving agent comprising sodium polymaleate containing 3% of acrylamide as a second component. The molecular weight was 4,000.
