    摘要： In a method of producing a sheet of paper and/or cardboard and similar products, prior to the formation of the sheet from a fibrous suspension, at least two dry strength agents are added to the suspension either separately in any order or mixed together and at one or more injection points, namely: a first agent corresponding to a product for Hofmann degradation in solution on a base (co)polymer comprising at least one non-ionic monomer which is selected from the group containing acrylamide and/or methacrylamide, N,N dimethylacrlamide and/or acrylonitrile; and a second agent corresponding to a (co)polymer having an anionic charge density greater than 0.1 meq/g. The Hofmann degradation product comprises an organic polymer produced at a concentration greater than 3.5% by weight, and preferably greater than 4.5% and the first and second agents are each introduced into the pulp suspension at a concentration of between 0.01 and 2% by weight of active polymer material in relation to the dry weight of the pulp suspension.

    摘要： The process of the present invention concerns manufacturing paper and paperboard employing two polymeric retention aids. These two polymeric retention aids should be added to the low consistency suspension, often referred to as the thin stock. The first polymeric retention aid is a water-soluble cationic polymer exhibiting an intrinsic viscosity of at least 6 dl/g. The second polymeric retention aid is a water-soluble cationic polymer exhibiting an intrinsic viscosity of between 4 and 9 dl/g. The cationic charge density of the second polymeric retention aid should be higher than that of the first polymeric retention aid. The process is particularly suitable for the manufacture of fine paper or multiply packaging paper which often contains filler.
