Abstract
A dimer fatty acid-polyether-reaction product prepared by reacting a composition containing at least 80 wt % of one or more dimer fatty acids with at least one polyether of application formula (I) in a molar ratio of 0.7/2.3 to 1.6/1.7. The reaction product has a number-average molecular weight of 4800 to 40000 g/mol and an acid number of less than 10 mg KOH/g.

A dimer fatty acid-polyether-reaction product prepared by reacting:
- (a) one or more dimer fatty acids with
- (b) at least one polyether of formula (I):
- where R is a C3 to C6 alkylene radical and n is selected such that the at least one polyether (b) possesses a number-average molecular weight of 2250 to 6000 g/mol,
- wherein components (a) and (b) are reacted in a molar ratio of 0.7/2.3 to 1.6/1.7, and wherein the resulting reaction product consists of units of components (a) and (b) and possesses a number-average molecular weight of 4800 to 40000 g/mol and an acid number of less than 10 mg KOH/g.
