    • Novel vinyl carbamates, prepared from vinyl chloroformate and amino acids and polymers containing from 5-100% of these novel vinyl carbamates are disclosed. These polymers act as sequestering agents and are useful as detergency builders. Detergent compositions incorporating the polymers can be prepared without use of phosphorus-containing detergent builders.Formulas for the novel carbamates and polymers are as follows:Vinyl carbamate compounds of the Formula: ##STR1## wherein a and b are independently 0, 1, or 2, or even greater; R is hydrogen methyl, ethyl or long chain alkyl, alkenyl or aryl and M is C.sub.1-4 alkyl, hydrogen, or a cation which forms a substantially water soluble salt with said compound at ambient temperatures; andPolymeric compounds of the formula: ##STR2## wherein a and b are independently 0, 1 or 2 or even greater; m is at least one; R is hydrogen, methyl, ethyl, or long chain alkyl, alkenyl or aryl and M is C.sub. 1-4 alkyl, hydrogen, or a cation which forms a substantially water soluble salt with said polymeric compound at ambient temperatures; andPolymeric compounds with repeating units of the structure: ##STR3## wherein a and b are independently 0, 1 or 2 or even greater; wherein m and n are at least one; R is hydrogen, methyl, ethyl, or long chain alkyl, alkenyl or aryl and M is hydrogen or a cation which forms a substantially water soluble salt with said polymeric compound at ambient temperatures or C.sub.1-4 alkyl and wherein A is a repeating unit having at least one copolymerized comonomer, said comonomers being selected from the group consisting of unsaturated carboxylic acids and their salts, esters and derivatives, unsaturated dicarboxylic acids and their salts, esters, and derivatives, unsaturated alcohols, unsaturated amines, unsaturated pyrrols, vinyl ethers, alkyl acrylates, alkenyl carboxylalkyl ethers, vinyl esters of carboxylic acids, olefins and furans.
