摘要： Method for the production of paper, cardboard and card by dewatering a paper stock with sheet formation in the presence of a retention agent system made of (i) at least one vinylamine unit-containing polymer in the form of the free bases, the salts and/or in quaternized form as sole cationic polymer, (ii) at least one linear anionic polymer having a molar mass Mw of at least 1 million and/or at least one branched anionic water-soluble polymer and/or bentonite and/or silica gel and (iii) at least one particulate, anionic, crosslinked, organic polymer having an average particle diameter of at least 1 µm and an intrinsic viscosity of less than 3 dl/g and also use of the retention agent system made of the components (i), (ii) and (iii) as additive in the production of paper, cardboard and card.
