실험 절차

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 was effected in the presence of ammonium persulfate at 100° C. for 5 h to obtain a dyeability-improving agent comprising sodium polymaleate having a molecular weight of 3,000.
