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 &#x3e;0:1 to &#x3c;1:1 [mol/mol]. Further provided herein is a process for preparing such polymers and derivatives of the polymers by quaternization, protonation, sulphation and/or phosphation.

Substoichiometric alkoxylated polyethers

The present invention relates to an ethoxylated polyethylenimine polymer consisting essentially of (a) a polyethyleneimine backbone, (b) a polyoxyethylene chain wherein the polyoxyethylene chain has an average of 1 to less than 40 ethyleneoxide units per unit of NH in the polyethyleneimine backbone, (3) a quaternization degree of from 50% to 100%.

Quaternized polyethylenimines with a high quaternization degree

The present invention relates to an ethoxylated polyethylenimine polymer comprising (1) a polyethyleneimine backbone, (2) a polyoxyethylene chain wherein the polyoxyethylene chain has an average of 40 to 90 ethyleneoxide units per unit of NH in the polyethyleneimine backbone, (3) a quaternization degree of from 1% to less than 50%.
