Abstract
The invention relates to a crosslinked, carboxylic acid-based copolymer having good water absorbability and biodegradability, and a method for producing it; to an unsaturated carboxylic acid polymer having good detergency and its use; and to a biodegradable builder, a detergent composition and a dispersant. The invention includes (1) a crosslinked product of a copolymer from a monomer component that comprises an unsaturated monocarboxylic acid monomer and a specific amount of a quinone; and (2) an unsaturated carboxylic acid polymer which gives specific peaks in proton nuclear magnetic resonance spectrometry, and which has a specific number-average molecular weight and has calcium ion-sequestering ability, or an unsaturated carboxylic acid polymer having a specific structure.
