Abstract: Polyetheramine are prepd. by condensing di- or polyamines (I) contg. 2-10 N atoms wich chlorohydrin ethers (II) prepd. from 1 mol divalent 2-5C alcohol, the ethoxylated adduct contg. up to 18 ethylene oxide units, glycerol or polyglycerol contg. up to 15 glycerol units and 2-8 mol epichlorohydrin at 110-200 degrees C in polar, water miscile solvents in the absence or extensive exclusion of water, adding an alkali(ne earth) metal base to neutralise >=20% of the HCl formed by the condensn. and post-condensing (I) is used in an amt. of 0.6-2.5 mol per mol. chlorohydrin gp. in (II). The aids are prepd. withou the necessity of having to graft components used during the condensn. with ethylene imine.
