Unsaturated carboxylic acid polymer, biodegradable builder, and detergent composition |
| abstract |
An unsaturated carboxylic acid polymer which has a calcium-trapping ability of 150 mg-CaCO3/g or higher, a degree of 28-day biodegradation of 40 % or higher, and a number-average molecular weight of 500 to 1,000,000; a process for producing an unsaturated carboxylic acid polymer which comprises copolymerizing an unsaturated carboxylic acid or a salt thereof 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 is excellent in the ability to trap calcium ions and biodegradability and is highly useful as a material for a builder. |
