Abstract: Method for producing paper, paperboard and cardboard with a high dry strength through the separate addition of a water-soluble cationic polymer and an aqueous dispersion of a water-insoluble polymer with an acid group fraction of no more than 10 Mol-% or an anionically adjusted aqueous dispersion of a non-ionic polymer to a paper pulp, dewatering the paper pulp and drying the paper product. It is preferable for the polymers to be added to a paper pulp that has a temperature of at least 40 °C.
