  • Publication number: 20070060495
    Abstract: A mixture comprising a surfactant and a cosurfactant is proposed, wherein the cosurfactant used is an amphiphilic polymer with the structural formula in which A? is an unbranched or branched alkyl, cycloalkyl, aryl or aralkyl radical having 1 to 60 carbon atoms, Y is S or O, A is a structural unit with the formula in which R1, R2, R3 and R4 independently of one another, are the substituents hydrogen, methyl, ethyl, n-propyl, octyl or phenyl, m is a running number in the range from 10 to 200, X is a structural unit with the formula in which the substituents R1, R2, R3 and R4 are the same as in the structural unit A, q=0 or q=1, B is a monomeric subunit based on ethylene oxide or a mixture of ethylene oxide and propylene oxide, n is a running number in the range from 20 to 500 and p=q+1.

  • Publication number: 20070041926
    Abstract: A mixture comprising a surfactant and a cosurfactant is proposed wherein the cosurfactant used is an amphiphilic comb polymer having a backbone with two or more side chains attached to the backbone, where the side chains differ from one another and/or the side chains differ from the backbone in their amphiphilic character.
