  • POLYMERIC SURFACTANT
    Publication number: 20160145382
    Abstract: Surfactant compositions including sulfonated polyester polyethers, and methods of making such compositions, are described. A diol is reacted with an anhydride having residual unsaturation, and the resulting polymer is sulfonated under mild acid-base conditions. Sulfonation occurs at the residual unsaturation. If maleic anhydride is used, sulfonation occurs at locations alpha to carbonyl carbons in the polymer.
