C., optionally under reduced pressure, up to an acid number of from 20 to 5. The resulting polycondensate is then oxyalkylated per carboxyl group using from 1 to 5 moles of an alkylene oxide, for example 1,2-propylene oxide and/or preferably ethylene oxide, in the presence of at least one tertiary amine catalyst from the group consisting of N-methylimidazole, diazabicyclo[2,2,2]octane, diazabicyclo[5,4,0]undec-7-ene and pentamethyldiethylenetriamine and mixtures thereof, in a quantity of from about 0.001 to 1.0 weight percent based on the weight of the polycondensate, at temperatures from about 100.degree. to 170.degree. C. and under a pressure of about 1 to 10 bar.
