Di- and other poly-sulfosuccinate esters of di- and other poly-hydroxyl aromatic propoxylated compounds in which, by way of illustration, both of the hydroxyl groups of a bisphenol, for instance, Bisphenol A, are etherified with a propylene oxide .alpha.-epoxide, the free hydroxyl groups of the resulting propoxylated bisphenol then being esterified with a sufficient amount of maleic anhydride whereby the resulting intermediate acid ester compound comprises di- and/or poly-maleic acid esters having free carboxyl groups which are then esterified with propylene oxide .alpha.-epoxide to produce a further intermediate having a free hydroxyl group at each of its terminal ends; and after which said last-mentioned intermediate is reacted to introduce at least two sulfosuccinated groups into the final compound, for instance, by reaction with aqueous bisulfite. Before treatment with bisulfite, the alkoxylated maleic acid ester having free hydroxyl groups can again be esterified with maleic anhydride and then with a propylene oxide .alpha.-epoxide at the terminal ends of the intermediate. These steps may be repeated one or more times dependent on the particular intermediate desired, before treatment with bisulfite. The novel di- and poly-sulfosuccinates of the present invention have utility as surfactants particularly for use in the emulsion polymerization of styrene-butadiene or carboxylated styrene-butadiene lattices for use in upholstery backings, carpet backings and related uses.

Aromatic base poly-sulfosuccinate esters

Unsymmetrical sulfosuccinate diesters in which one carboxyl group of the sulfosuccinate is esterified with an alcohol, for instance, a C.sub.8 -C.sub.12 aliphatic monohydric alcohol such as octyl or dodecyl alcohol, or with an ethoxylated or propoxylated alkyl phenol, and in which the other carboxyl group is esterified by reaction with ethylene oxide, and method of preparation of such diesters. The said diesters have utility as surfactants, such as detergents and emulsifiers.

Unsymmetrical sulfosuccinate diesters

Sulfosuccinate diesters in which one carboxyl group of the sulfosuccinate is esterified with an ethoxylated or propoxylated non-tertiary monoamine, for instance, a C.sub.8 -C.sub.18 fatty amine, ethoxylated with 3 or 4 moles of ethylene oxide, to form a hydroxyl-containing tertiary amine, and in which the other carboxyl group of the sulfosuccinate is esterified with an .alpha.-monoepoxide such as propylene oxide, or higher .alpha.-monoepoxides, and method of preparation of such sulfosuccinate diesters. The said sulfosuccinate diesters have utility as surfactants, such as detergents and emulsifiers.

Sulfosuccinate diesters

Sulfosuccinate ester-amides in which one carboxyl group of the sulfosuccinate is amidified with an aliphatic non-tertiary amine, for instance, a C.sub.8 -C.sub.12 aliphatic amine such as octyl or dodecyl amine, and in which the other carboxyl group of the sulfosuccinate is esterified by reaction with an .alpha.-monoepoxide such as propylene oxide, or higher .alpha.-monoepoxides, and method of preparation of such sulfosuccinate ester-amides. The said sulfosuccinate ester-amides have utility as surfactants, such as detergents and emulsifiers.
