Abstract

Abstract Sulfosuccinic acid derivatives having the formula: ##STR1## wherein R is a member selected from the group consisting of: ##STR2## where R 1 and R 2 are members selected from the group consisting of hydrogen and alkyl having from 1 to 16 carbon atoms, and the sum of the carbon atoms in R 1 and R 2 is from from 9 to 16, R 3 is a member selected from the group consisting of hydrogen and methyl, R 4 is alkyl having 1 to 5 carbon atoms, M 1 and M 2 are cations selected from the group consisting of alkali metals, ammonium, alkylammonium having 1 to 4 carbon atoms in the alkyl and alkylolammonium having 2 to 4 carbon atoms in the alkylol and m is an integer from 1 to 10. These sulfosuccinic acid derivatives are useful as emulsifying agents, particularly in the production of emulsion polymers.
