Abstract

An alkoxylated polyamidoamine obtainable by a) reacting a polycarboxylic compound having a total number TN of carboxylic groups of 3 to 10 with a primary diamine of formula I H2N—Z—NH2 wherein Z represents a bond or an organic group with 1 to 20 carbon atoms in a ratio of 0.3 TN to TN mols of the diamine per 1 mol of the polycarboxylic compound and b) alkoxylating the product obtained in a) with at least 0.5 mol of alkyleneoxide per 1 mol of primary amino groups.
