Abstract
This invention provides detergent compositions utilizing divinyl ether/maleic anhydride polymers as detergent builders or co-builders. This invention also provides novel polymers of divinyl ether, maleic anhydride and at least one copolymerizable comonomer, selected from the group consisting of alkyl ethers, alkyl acrylates, carboxyalkyl ethers, vinyl esters of C.sub.1 and C.sub.3 or greater carboxylic acids, carboxylic acids, dicarboxylic acids and their esters, and olefins, and detergent compositions utilizing these novel polymer compositions as detergent builders.
