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: O,N-Disubstituted hydroxylamines are prepared by reacting O-substituted ketoximes with hydrogen in the presence of a platinum catalyst at from 35 to 50 bar, in a medium containing a mineral acid. The O,N-disubstituted hydroxylamines I obtained by the process of the invention are valuable starting materials for the preparation of dyes, crop protection agents and drugs.

Abstract: In a cationic modification process for starch, starch is reacted with polymers that contain amino and/or ammonium groups in an aqueous medium at temperatures from 115 to 180 DEG C under an increased pressure and in the absence of oxidisers, polymerisation initiators and alkali. The reaction is conducted so that maximum 10% by weight starch has its molar weight reduced. Also disclosed is the use of the thus obtained reaction products as dry strength agents for paper.
