    Abstract: The invention relates to a process for the preparation of hydroxyalkylated polyethyleneimines by hydroxyalkylation of polyethyleneimines in one or two procedural stages to form reaction products which contain 1 to 200 mol alkylene oxide groups per NH group in the polyethyleneimine. In the one-stage process, there are anhydrous polyethyleneimines and 1 to 20 mol %, in relation to the polyethyleneimines, of at least one anhydrous base, or aqueous solutions of said substances are dehydrated and after removing all the water are reacted at temperatures above 135-150 DEG C with at least one alkylene oxide. Alternatively, in the two-stage process, in the first stage polyethyleneimine is reacted at temperatures of from 80 to 100 DEG C with 0.7 to 0.9 mol, in relation to a mol NH group in the polymerisate, of at least one alkylene oxide in an aqueous solution, and in the second stage the reaction product obtained in the first step is reacted in the presence of 1 to 20 mol %, in relation to polyethyleneimine, of an alkaline catalyst in the absence of water at temperatures of from 120 to 150 DEG C with at least one alkylene oxide to form hydroxyalkylated polyethyleneimines which contain 1 to 200 mol of alkylene oxide groups per NH group in the polyethyleneimine. The consequent alkoxylated products are only slightly coloured.
