Abstract: Water-soluble, nitrogen-containing condensates are prepared by reacting a cross-linking agent, obtained by (a) condensing 1 mole of a dicarboxylic acid of 4 to 10 carbon atoms with from 1 to 2 moles of a polyalkylenepolyamine, having 3-10 basic nitrogen atoms in the molecule, to give a polyamidoamine and (b) reacting the polyamidoamine with epichlorohydrin and/or dichlorohydrin in aqueous solution at a pH of from 4.5 to 8.5 and at below 100 DEG C., from 1 to 130 parts by weight of epichlorohydrin and/or dichlorohydrin being employed per 100 parts by weight of the polyamidoamine from (a), with ammonia, a primary amine, a polyamine containing 2 to 4 N atoms, a polyether-amine or a polyamidoamine in aqueous solution at below 100 DEG C. The condensates are used as retention aids, flocculants and drainage aids in papermaking.

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.
