Abstract
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 1 and C 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
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 1 -C 12 alkyl substituent, or a C 5 -C 12 cycloalkyl substituent having at least one five- or six-membered ring, or a combination thereof.
Claim 2
Dependent Claim
81 words
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 1 -C 12 alkyl substituent, or a C 5 -C 12 cycloalkyl substituent having at least one five- or six-membered ring, or a combination thereof.
Claim 3
Dependent Claim
120 words
The detergent composition of claim 1, wherein the builder is a polymer further comprising a repeating unit of the structure: ##STR5## wherein A is a repeating unit derived from at least one copolymerized comonomer selected from the group consisting of alkenyl alkyl ethers, alkyl acrylates, alkenyl carboxyalkyl ethers, vinyl esters of carboxylic acids, unsaturated carboxylic acids, unsaturated dicarboxylic acids and their esters, and olefins; X is H, or an alkali metal ion, ammonium ion, or hydroxyethylammonium ion, or a C 1 -C 12 alkyl substituent, or a C 5 -C 12 cycloalkyl substituent having at least one five- or six membered ring, or a combination thereof; m and n are greater than 1; and p is from 5 to 4,000.
Claim 4
Dependent Claim
100 words
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.
Claim 5
Dependent Claim
100 words
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.
Claim 6
Dependent Claim
15 words
The detergent composition of claim 1, wherein the composition further comprises more than one surfactant.
Claim 7
Dependent Claim
15 words
The detergent composition of claim 1, wherein the composition further comprises more than one builder.
Claim 8
Dependent Claim
21 words
The detergent composition of claim 1, wherein the builder is a sodium, potassium, ammonium, monoethanolamine or triethanolamine salt of the polymer.
Claim 9
Dependent Claim
28 words
The detergent composition of claim 1, comprising from about 0.5 to 30% by weight of a surfactant and from about 1 to 65% by weight of the builder.
Claim 10
Independent Claim
95 words
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 1 -C 12 alkyl substituent or a C 5 -C 12 cycloalkyl substituent having at least one five-or six-membered ring, or a combination thereof.
