Abstract: A process for removing anionic compounds from water which is recycled in manufacturing processes, and from waste water, by adding (1) water-soluble products obtained by reacting an alkylating agent, having an aromatic substituent, with a cationic polyelectrolyte and (2) mineral adsorbents and/or a magnesium salt, aluminum salt or iron salt, with formation and flocculation of water-insoluble reaction products.

Abstract: 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: A process for the manufacture of paper having a high dry strength and a low wet strength, by treating the surface of the paper with an aqueous solution of an alkali metal and/or alkaline earth metal salt of a copolymer of (a) from 90 to 30% by weight of acrylic acid and/or methacrylic acid and (b) from 10 to 70% by weight of acrylonitrile, methacrylonitrile, acrylamide and/or methacrylamide, with or without (c) up to 30% by weight of an ester of acrylic acid or methacrylic acid, which copolymer has a viscosity of from 5 to 100 mPas in 2% strength aqueous solution at 20.degree.C. and drying the impregnated paper. The copolymer is generally employed in an amount of from 1 to 4% by weight, based on dry paper, and increases the dry strength of the paper without substantially increasing the wet strength.

Abstract: 1,165,394. Nitrogen-containing condensation products. BADISCHE ANILIN- & SODAFABRIK A.G. 7 Feb., 1967 [8 Feb., 1966], No. 5790/67. Heading C2C. [Also in Division C3] Water soluble condensates containing a chlosohydrin group are prepared by reacting 1 mole of an alkylene polyamine with from 1 to 1À3 α moles of #Àcaprolactam, α being the number of amino groups in the polyamine. The resultant amino-containing intermediate is then reacted, in aqueous soln. or suspension with 1 to 2.5 moles of epichlorohydrin per mole of basic amino groups in the intermediate until a 15% aq. soln. has a viscosity between 30 and 100 cp. at 20‹ C., the soln. is adjusted to a pH of
