Zusammenfassung:	Provided herein are polymers obtainable by a process including the steps a) and b) described below. In Step a) at least one component a1) is condensed to obtain a polyether having remaining hydroxyl groups. Component a1) is at least one component selected from N-(hydroxyalkyl) amins according to formula (Ia) and/or (Ib) as defined below. Besides component a1), further components can be present in the condensation step a). In step b) a part of the remaining hydroxyl groups are reacted with at least one alkylene oxide. The alkoxylation according to step b) is carried out in a substoichiometric way. The ratio of i) the alkylene oxide versus ii) the sum of the amount of the remaining hydroxyl groups is >0:1 to
