    摘要： A process for the manufacture of polyalkylenepolyamines by reacting a primary or secondary amine with a compound of the formula ##STR1## where X is --Cl, --Br, or --OSO.sub.3 H and R.sup.1 and R.sup.2 are H or saturated alkyl of 1 to 4 carbon atoms, and with at least the stoichiometric amount, based on the compound of the formula I, of an aqueous solution, of from 15 to 45 percent strength, of an alkali metal hydroxide or alkaline earth metal hydroxide, at from 60.degree. to 200.degree. C., cooling the reaction mixture to a temperature at which 2 aqueous phases form, and separating off the upper phase, containing polyalkylenepolyamnines. The rate of reaction can be increased by adding catalytic amounts of compounds which initiate the polymerization of alkyleneimines.

    摘要： Water-soluble benzylated polyamidoamines which contain from 0.1 to 0.9 mole of benzyl groups per equivalent of nitrogen, and onto which from 20 to 400 parts by weight of ethyleneimine or propyleneimine have been grafted per 100 parts by weight of polyamidoamine, processes for the preparation of the materials, and the use of the materials as cationic assistants in processes for coloring paper with acid dyes and/or direct dyes in an aqueous medium. The papers obtained show a high color strength, with substantially no two sidedness of the coloration.

    摘要： Cotton and cotton-containing fabrics are desized in strongly alkaline aqueous solution with an alkali metal hypochlorite by a process in which from 0.5 to 8.0 g/l of a tertiary hydroxyalkylamine which is soluble in aqueous alkaline solution, of an oxyethylated and/or oxypropylated ethylenediamine, of an oxyethylated polyethyleneimine, of malonic acid, of cyanuric acid, of a cyanuric acid derivative, of a urea derivative, of cyanoguanidine, of oxazolidone, of pyrrolidone, of N-methylpyrrolidone, of N-methylimidazole or of a mixture of these is added to the aqueous bath, as an activator for the hypochlorite. Activators for hypochlorite are used in the desizing of cotton and cotton-containing fabrics in strongly alkaline aqueous solutions.
