Abstract: O.Z. 0050/035031 A process for coloring paper with an acid dye and/or direct dye in an aqueous medium in the presence of a water-soluble reaction product of an alkylating agent, possessing an aromatic substituent, with a cationic polyelectrolyte. The process gives papers with high color strength and substantially avoids cylinder twosidedness of the coloration.

Abstract: Water-soluble, crosslinked nitrogen-containing condensation products, the viscosity of which, in aqueous solution, increases with increasing temperature, are obtained by reacting a block copolymer of the formula: where R is , n being from 0.75 to 3, , , or , x is from 50 to 250, y is from 20 to 100, the ratio of x to y is from 6.5 to 1 : 15, with compounds having at least four basic NH groups in a weight ratio of from 0.8 : 1 to 30 : 1. The products are added to aqueous systems, e.g. polymer solutions and polymer dispersions, to improve the viscosity characteristics.

Abstract: Production of water-sol?ble crosslinked auxiliari?s for the papermaking industry by reacting(a) one equivalent of NH groups of a polyalkylene polyamine having from 15 to 500 alkyleneimine units with(b) from 0.001 to 0.08 mole of a reaction product obtained from a polyalkylene oxide having from 8 to 100 alkylene oxide units with epichlorohydrin, in aqueous solution at a temperature of from 20.degree. to 100.degree.C. The viscosity of an aqueous solution containing 20% by weight of the crosslinked auxiliaries is from 300 to 1,500 centipoises (20.degree.C).

Abstract: A process for the manufacture of polyalkylenepolyamines by reacting a primary or secondary amine with a compound of the formula (I) where X is -Cl, -Br, or -OSO3H and R1 and R2 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 DEG to 200 DEG 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.
