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.
