Reaction Steps

The obtained polymer (179.2 g) is introduced into an autoclave and 9.29 g potassium hydroxide (50% solution in water) and 27.5 g Pluriol A 1000 E of BASF AG, Ludwigshafen (Germany), which is the monomethylether of polyethylene glycol with an average molecular weight of 1000 g/mol. The resulting mixture is flushed with nitrogen and subjected to vacuum increasing the temperature to 90° C. at 20 mbar for 2 hours to remove the water. 792 g ethylene oxide are added at 90° C. The mixture is allowed to post-react for 3 hours. The polymer composition is cooled to 80° C. and flushed with nitrogen. A brown solid is obtained (950 g), consisting of a polymer from diethylenetriamine and adipic acid with 30 mol ethylene oxide per mol NH bond.
