    Abstract: PROBLEM TO BE SOLVED: To provide a water-absorbing foamy crosslinked polymer.
    SOLUTION: The process for producing the polymer comprises a first step (I) of foaming a polymerizable aqueous mixture of (a) a monoethylene unsaturated monomer having an acid radical in which at least its 50 mol% is neutralized, (b) optionally other monoethylene unsaturated monomer, (c) a crosslinking agent, (d) an initiator, (e) 0.1-20 wt.% of at least one kind of surfactant, (f) optionally at least one kind of solubilizer, and (g) optionally, a thickener, foam stabilizer, polymerization regulator, filler and/or foam nucleus-forming agent, and of dispersing fine foams of inactive gas into the radical to carry out foaming, and a second step (II) of forming a foamy hydrogel and optionally adjusting a water content of the foamy polymer to 1-60 wt.% to polymerize the foamed mixture.

    Abstract: The invention relates to a method for producing paper, paperboard and cardboard in the presence of an aqueous suspension of components containing fine-particles of filler material. The fine-particle filler materials are covered at least partially with water-soluble amphoteric copolymers. Said method consists in adding to the fibre suspension, prior to the formation of the sheet, and in addition to the aqueous suspension of components containing fine-particles filler material, at least one cationic and/or amphoteric polymer which, as a structural element, does not contain any ester unsaturated carboxylic acids with quaternised amino alcohols.

    Abstract: The invention relates to the use of cross-linked polymers which have a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution) and which contain polymerised monoethylenic unsaturated monomers that contain acid groups and/or the alkali salts or ammonium salts thereof and optionally additional polymerised monoethylenic unsaturated monomers. Said cross-linked polymers are used as an additive for compact, particle-shaped washing and cleaning agents for increasing the disintegration rate when being brought into contact with water. The invention also relates to the use of compact, particle-shaped washing and cleaning agents which contain cross-linked polymers with a water absorbency of less than 30 g/g polymer (determined in a 0.9 wt. % aqueous common-salt solution).
