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.
Claims8
A detergent composition, comprising from about 0.5 to 65% by weight of a surfactant and from about 1 to 80% by weight of a builder, wherein the builder is a polymer comprising a repeating unit of the structure:
- ##STR4## wherein X is H, or an alkali metal ion, ammonium ion, or hydroxyethylammonium ion, or a C.sub.1 -C.sub.12 alkyl substituent, or a C.sub.5 -C.sub.12 cycloalkyl substituent having at least one five- or six-membered ring, or a combination thereof.
A detergent composition, comprising from about 0.5 to 65% by weight of a surfactant and from about 1 to 80% by weight of a builder, wherein the builder is a polymer, comprising a repeating unit of the structure:
- ##STR6## wherein A is a repeating unit derived from at least one copolymerized comonomer selected from the group consisting of alkenyl alkyl ethers, alkenyl alkyl acrylates, alkenyl carboxyalkyl ethers, vinyl esters of carboxylic acids, unsaturated carboxylic acids, unsaturated dicarboxylic acids and their esters, and olefins;
- m is greater than 1;
- n is zero or greater;
- and p is from 5 to 4,000.
A method for washing fabric, comprising agitating the fabric in the presence of water and a detergent composition, comprising from about 0.5 to 65% by weight of a surfactant and from about 1 to 80% by weight of a builder, wherein the builder is a polymer comprising a repeating unit of the structure:
- ##STR7## wherein X is H, or an alkali metal ion, ammonium ion, or hydroxyethylammonium ion, or a C.sub.1 -C.sub.12 alkyl substituent or a C.sub.5 -C.sub.12 cycloalkyl substituent having at least one five-or six-membered ring, or a combination thereof.
