Date Jul. 17, 1997A process for the preparation of water-soluble, amino-containing condensates and adducts having a greater drainage and retention effect in papermaking, in which from 5 to 95% by weight of the condensates or adducts are separated off as permeate from solutions of water-soluble, amino-containing condensates or adducts by ultrafiltration through membranes and the amino-containing condensates or adducts having improved efficiency are, if required, isolated from the retentate, and the high molecular weight polymer fractions contained in the retentate are used as retention aids, drainage aids and fixing compositions in papermaking, as promoters in the sizing of paper with alkyldiketenes, as flocculants for sewage sludges, as adhesion promoters in the production of laminated films, as additives for hair and skincare compositions and as compositions for immobilizing anionic active ingredients.

Abstract: The invention relates to a method for producing paper by dehydrating, on a paper machine, paper pulp containing processing chemicals. According to said method, the paper machine wire is supplied, via a headbox, with a principal stream of paper pulp and a diluting stream consisting of returned water, containing at least 5 weight percent of the processing chemicals and accounting for between 5 and 35 % of the total headbox supply. The papers produced in this way have an excellent formation cross section and outstanding ash distribution.

Abstract: The invention relates to a process for producing paper and cardboard by dehydration of pulps, forming sheets and drying said sheets. Polyethylene imines of a molar mass Mw of greater than 500 000 or polymers containing vinyl amine units and having a molar mass of 5000 to 3 million are added to the pulps and subsequently, polymers containing cationic polyacrylic amides or vinyl amine units are added to said pulps, the molar masses Mw of the polymers being at least 4 million in each case. The pulp is then subjected to at least one shearing stage and flocculates by addition of bentonite, colloidal silicic acid or clay.

Abstract: The disclosure concerns a method of producing water-soluble condensates and addition products containing amino groups and possessing enhanced de-watering and retention properties in paper production. Between 5 and 95 wt % of the condensates or addition products are removed as a permeate from solutions of water-soluble condensates or addition products containing amino groups by ultrafiltration through membranes and the condensates or addition products containing amino groups are if necessary isolated more efficiently from the retentate. The high-molecular polymer components contained in the residue are used as retention, de-watering and fixing agents in paper production, as promotors in gluing paper with alkyl diketenes, as flocculents for sewage sludges, as adhesives in the production of composite films, as additives to hair and skin conditioners and as an agent for immobilising anionic active substances.
