Reaction Steps
Subsequently, 704 g of the resulting 10 mol ethylene oxide adduct was subjected to an esterification reaction with 100 g of maleic anhydride at 80° C. for 2 hours. Thereafter, 300 g of water was added to this reaction mixture and then neutralized with an aqueous solution of sodium hydroxide at an internal temperature of 30° C. or lower. Further, the resulting mixture was subjected to a sulfonation reaction at 70° C. for 3 hours by introduction of 120 g of sodium bisulfite to give a composition K as an example of the present invention.
