摘要： The invention relates to a method for preparing aqueous furnish to be used in paper product manufacturing. In the method aqueous furnish is prepared by making a fiber suspension, and cationic natural polymer (S), alum (A) and anionic nanofibrillar cellulose (F) are added to the aqueous furnish in a short circulation of a paper or board machine.

摘要： The invention relates to a finely divided, starch-containing aqueous polymer dispersion which is obtainable by free radical emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one redox initiator and starch, wherein the ethylenically unsaturated monomers comprise (a) from 30 to 65% by weight of acrylonitrile and/or methacrylonitrile, (b) from 35 to 60% by weight of at least one C1-C12-alkyl acrylate and/or at least one C1-C12-alkyl methacrylate, (c) from 0 to 35% by weight of at least one other ethylenically unsaturated copolymerisable monomer, in which the sum of (a), (b) and (c) totals 100%, and in which the aqueous polymer dispersion comprises, (d) from 10 to 55% by weight of an ionic tapioca starch, in which the weight of (d) is based on the total solids of components (a), (b), (c) and (d) of the aqueous polymer dispersion. The invention also relates to a process for the manufacture of the finely divided, starch containing aqueous polymer dispersions and also to the use of said finely divided starch containing aqueous polymer dispersions as a size for paper, board and cardboard.

摘要： Methods, processes, and compositions for improving sizing efficiency in a paper-making process are provided. Pulp slurry is treated by using alkenyl succinic anhydride that is emulsified with a polymer emulsifier. The emulsified alkeny succinic anhydride is used in conjunction with paper-making filler particles that are modified with hydroxyl-containing hydrocarbon natural polymer polysaccharide.

摘要： The invention provides methods and compositions for increasing the dry strength of paper. The invention utilizes a tailored strength agent whose size and shape is tailored to fit into the junction points between flocs of a paper sheet. The strength agents is in contact with the slurry for just enough time to collect at the junction points but not so much that it can migrate away from there.
