Abstract: Paper, board and cardboard are produced by adding (i) at least one retention aid and (ii) ionic, water-insoluble, uncrosslinked, organic microparticles which have an average particle size of less than 500 nm and a content of polymerized ionic monomers of less than 1% by weight or water-insoluble, uncrosslinked, organic microparticles having an average particle size of less than 500 nm and a content of polymerized ionic monomers of not more than 10% by weight, which are obtainable by polymerizing the monomers in the presence of silica, waterglass, bentonite and/or mixtures thereof, to a paper stock and draining the paper stock over a wire.

Abstract: The invention relates to a process for producing paper sheets having a basis weight of at least 300 g/m2, said process comprising draining a paper pulp comprising waste paper on a wire, forming of the sheets and drying the sheets, wherein the draining of the paper pulp on the wire and the forming the sheets is carried out in the presence of a retention and drainage aid system which is a combination of at least two polymers as sole retention and drainage aids and which consists of: component (a): at least one amino-containing polymer, wherein the amino containing polymer is a polyethylenimine or a modified polyethylenimide obtained by reacting a polyamidoamine compound with a polyalkylene oxide derivative whose terminal hydroxyl groups have been reacted with epichlorohydrin, and component (b): at least one cationic polyacrylamide consisting of either at least one branched cationic polyacrylamide having an ionic regain greater than 20% or at least one branched cationic polyacrylamide having an ionic regain greater than 20% in combination with a linear polyacrylamide.
