Polymer, which can be manufactured by reacting (A) at least one polymer, which can be manufactured by reacting (a) dimeric fatty acids with (b) at least one polyether of the general structural formula (I) in the that R is a C3 to C6 alkylene radical and n is correspondingly chosen such that said polyether has an arithmetic average of molecular weight of 450 to 2200 g / mol, components (a) and (b) are used in a molar ratio from 0.7 / 2.3 to 1.3 / 1.7 and the resulting polymer has an arithmetic average molecular weight of 1500 to 5000 g / mol and an acid number <10 mg of KOH / g, (B) per at least one polyether of the general structural formula (II) in which R is a C3 to C6 alkylene radical and n is correspondingly chosen that said polyether has an arithmetic average of molecular weight of 250 to 3000 g / mol, (C ) at least one compound with at least one functional group that has the ability to form anions and / or at least one anionic group, and at least one, in particular at least two functional groups that have the ability to react with isocyanates, in which the compound is different from (A) and (B), (D) by at least one polyisocyanate, and (E) if necessary at least one mono- or diol, which is different from (A), (B) and (C), (F) at least one compound with more than two functional groups that have the ability to react with isocyanates, in which the compound is different from (A), (B) and (C), and if necessary neutralization of the groups of component (C) that have the ability to form anions |
