Branched polyesters with sulfonate groups

摘要

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.

1. A detergent or cleaner for textiles comprising:
0.1 to 99% by weight of at least one surfactant selected from the group consisting of an anionic surfactant, a nonionic surfactant, an amphoteric surfactant and a cationic surfactant; and a mixture comprising the branched polyester with sulfonate groups obtained by a process comprising:
reacting an α,β-olefinically unsaturated dicarboxylic acid (A2),a tri- or higher-functional alcohol (By),optionally a difunctional alcohol (B2) or difunctional carboxylic acid (C2) without α,β-olefinically unsaturated bonds, andoptionally a fatty acid or fatty alcohol, to obtain an intermediate branched polyester; and subsequently reacting the intermediate branched polyester with hydrogen sulfite, wherein a molar amount of hydrogen sulfite is at most 95 mol %, based on an amount of the α,β-olefinically unsaturated dicarboxylic acid (A2).
