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: Aqueous slurries of finely divided fillers which are at least partly coated with polymers and which are obtainable by treating aqueous slurries of finely divided fillers with at least one water-soluble amphoteric copolymer whose structures are identified in the specification are used as an additive to the paper stock in the production of filler-containing paper, filler-containing cardboard or filler-containing board by draining of the paper stock.

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.
