Abstract: Aqueous pigment slurries which contain up to 80 % by weight of a finely divided pigment in dispersed form and from 0.1 to 5 % by weight of a polyalkylenepolyamine having a molecular weight of at least 300 or water-soluble reaction products of (a) polyalkylenepolyamines having a molecular weight of at least 300 and/or polyamidoamines grafted with ethyleneimine and (b) bifunctional or polyfunctional crosslinking agents which have a halohydrin, glycidyl, aziridine or isocyanate unit or a halogen atom as a functional group, the reaction products, in 25 % strength by weight aqueous solution at 20.degree.C, having a viscosity of at least 100 mPa.s, are used as an additive to the paper stock in the production of fillercontaining paper.

Abstract: Antiespumantes y/o aireadores a base de dispersiones de aceite-en-agua, que contienen en la fase de aceite hidrófoba al menos un compuesto eficaz como antiespumante y/o aireador, caracterizados porque las dispersiones de aceite en agua contienen de un 0, 01 hasta un 3 % en peso de un copolímero anfífilo, hidrosoluble y que contiene grupos ácido con una masa molecular de 1000 hasta 100 000, formado por (a) monómeros hidrófobos monoetilénicamente insaturados, y (b) ácidos carboxílicos monoetilénicamente insaturados, ácidos sulfónicos monoetilénicamente insaturados, ácidos fosfónicos monoetilénicamente insaturados o sus mezclas, o una sal hidrosoluble de los mismos como estabilizante.

Abstract: Paper, board and cardboard having high dry strength are produced by the addition of cationic, anionic and/or amphoteric starch as dry strength agents to the paper stock and drainage of the paper stock with sheet formation in the presence of cationic polymers as retention aids for starch, and cationic polymeric retention aids are used for increasing the retention of dry strength agents comprising cationic, anionic and/or amphoteric starch in the production of paper, board and cardboard.

Abstract: A process for modifying starch by heating starch in an aqueous medium to temperatures above the gelatinization temperature of said starch comprises effecting said modifying of said starch in the presence of(a) a polymeric cationizer selected from the group consisting of the polymers containing vinylamine units and having molar masses of up to 1 million, the polyethyleneimines, the polydiallyldimethylammonium chlorides, the condensates of dimethylamine with epichlorohydrin or dichloroalkanes, the condensates of dichloroethane and ammonia, and the mixtures thereof, and(b) polymeric papermaking drainage aids selected from the group consisting of the water-soluble crosslinked polyamidoamines with or without an ethyleneimine graft, the polymers containing acrylamide and/or methacrylamide units and having molar masses of more than 1 million, the polymers containing vinylamine units and having molar masses of more then 1 million, and the mixtures thereof.
