- AO is an alkylenoxy group containing 2 to 4 carbon atoms,
- m represents an integer between 1 and 20, limits inclusive,
- n represents an integer between 1 and 20, limits inclusive, with
- B) a dicarboxylic acid, or a derivative thereof, chosen from oxalic acid, malonic acid, succinic acid, glutaric acid, glutaconic acid, adipic acid, muconic acid, pimelic acid, phthalic acid and isomers thereof, tetrahydrophthalic acid, malic acid, maleic acid, fumaric acid, suberic acid, mesaconic acid, sebacic acid, azelaic acid, tartaric acid, itaconic acid, glutinic acid, citraconic acid, brassylic acid, dodecanedioic acid, traumatic acid, thapsic acid, the corresponding acid chlorides thereof, the corresponding methyl or ethyl esters thereof, and the corresponding cyclic anhydrides thereof, and mixtures thereof;
- and with
- C) an (alkyl)alkanolamine chosen from triethanolamine, methyldiethanolamie, ethyldiethanolamine, propyldiethanolamine, butyldiethanolamine, isobutyldiethanolamine, pentyldiethanolamine, phenyldiethanolamine, hexyldiethanolamine, heptyldiethanolamine, and also the corresponding alkoxylation products thereof.
