Reaction Steps

The obtained polymer (375 g) is introduced into an autoclave and 26.5 g potassium hydroxide (40% solution in water) and 76.8 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. 344.8 g ethylene oxide are added at 90° C. in portions during 2 hours. The mixture is allowed to post-react for 3 h. The polymer composition is cooled to 80° C. and flushed with nitrogen. A light brown viscous liquid is obtained (690 g), consisting of a polymer from diethylenetriamine and adipic acid with 5.3 mol ethylene oxide per mol NH bond. The iodine color number is 1.0 (10% in water).
