  • Patent number: 10196286
    Abstract: A method may be provided for removing fluorinated organic compounds from contaminated fluids by means of a kit that comprises a first and a second adsorbent component, or only by means of the first adsorbent component alone. The second adsorbent component is a solid adsorbent; the first adsorbent component is a chemical compound that contains a lipophilic group and a hydrophilic group, or contains such a compound in dissolved form, wherein the hydrophilic group contains at least one cationic group and wherein the lipophilic group is selected from alkyl groups that comprise at least one octylene unit, from aryl groups, and from aralkyl groups. The contaminated fluid may be brought in contact with the first adsorbent component, and optionally the fluid is also brought in contact with the second adsorbent component. The adsorbent component(s) may be removed from the fluid together with the adsorbed fluorinated organic compounds.

  • Publication number: 20080302497
    Abstract: The present invention relates to flat paper products having an increased relative wet strength and softness, a method for the production of the same and also the use of paper products of this type in the form of tissue products. This is achieved by a cross-linkage of the cellulose fibres contained in the paper product with a cationic graft copolymer which is constructed on the basis of polyethyleneoxide- or polyethyleneglycol segments and polyethyleneimine segments.

  • Publication number: 20040236017
    Abstract: The invention relates to a method for the production of grafted copolymers with a skeleton formed from starch or the derivatives thereof. Production occurs by means of tert-alkylazocyanocarboxylic acid esters of starch which are coupled by radical reaction with vinyl monomers. The invention also relates to grafted copolymers of starch, the dispersions thereof and the use of said grafted copolymers.
