摘要： PROBLEM TO BE SOLVED: To obtain a polymer excellent in a calcium ion scavenging capacity and biodegradability as well and useful as a detergent builder or for a dispersant by copolymerizing an unsaturated carboxylic acid (salt) with acrylamide and reacting the copolymer with a benzoquinone. SOLUTION: An unsaturated carboxylic acid or a salt thereof represented by the formula (wherein X is H, an alkali metal, or an ammonium group; Y is H or COOX; and R is H or methyl) is copolymerized with acrylamide in the presence of a polymerization initiator prepared by combining hydrogen peroxide with at least one reducing agent selected from the group consisting of an iron ion, a copper ion, a zinc ion, a nickel ion, ascorbic acid, and saccharin, and the obtained copolymer is reacted with a benzoquinone to obtain an unsaturated carboxylic acid polymer having a number-average molecular weight of 500-1,000,000. It is desirable that the total of the copolymerized acrylamide and the copolymerized benzoquinone accounts for 0.5-20 wt.% of the total weight of the copolymer.
