Abstract
Branched polyesters with sulfonate groups obtainable by the reaction of the components A, B, optionally C and optionally D to give branched polyesters, where the component A is selected from the group of α,β-olefinically unsaturated dicarboxylic acids, and the component B is selected from the group of tri- or higher-functional alcohols, the optional component C is selected from the group of difunctional alcohols or of difunctional carboxylic acids without α,β-olefinically unsaturated bonds, the optional component D is selected from fatty acids or fatty alcohols, and the subsequent reaction of the resulting branched polyesters with hydrogen sulfite, where the molar amount of hydrogen sulfite is at most 95 mol %, based on the amount of α,β-olefinically unsaturated dicarboxylic acid.
