    摘要: Provided are an unsaturated carboxylic acid polymer having a degree of calcium-sequestering ability of at least 150 mg CaCO3/g, a degree of 28-day biodegradability of at least 40%, and a number-average molecular weight of from 500 to 1,000,000; a process for producing the unsaturated carboxylic acid polymer by copolymerizing an unsaturated carboxylic acid or its salt with a quinone in the presence of a polymerization initiator; a builder comprising the polymer; a detergent composition comprising the builder and a surfactant; and a dispersant comprising the polymer. The polymer has good calcium ion-sequestering ability and good biodegradability, and is highly useful as a material for builders.
