Method for increasing the dry strength of paper, paperboard, and cardboard

Process for the production of paper, board and cardboard having high dry strength by addition of at least one water-soluble (a) polymer comprising vinylamine units and at least one (b) polymer comprising ethylenimine units and at least one water-soluble polymeric anionic compound to a paper stock, draining of the paper stock with sheet formation and drying of the paper products, the water-soluble cationic polymers (a) and (b) being metered in any sequence or as a mixture into a paper stock, and papers which are obtainable by this process.

Process for increasing the dry strength of paper, board and cardboard

The invention relates to a process for producing paper, board and cardboard of high dry strength by separately adding a polymer comprising vinylamine units and a polymeric anionic compound to a paper pulp, dewatering the pulp and drying the paper products, which comprises using as polymeric anionic compound at least one copolymer obtainable by copolymerizing 

Method for producing high dry strength paper, paperboard or cardboard

Process for the production of paper, board and cardboard having high dry strength by separate addition of a polymer comprising vinylamine units and of ligninsulfonic acid and/or a ligninsulfonate to a paper stock, draining of the paper stock and drying of the paper products.
