  • SUPERABSORBENT POLYMER WITH HIGH PERMEABILITY
    Publication number: 20070066718
    Abstract: The invention relates to absorptive, crosslinked polymers which are based on partly neutralized, monoethylenically unsaturated monomers carrying acid groups wherein the absorptive crosslinked polymer may be coated with a thermoplastic polymer, and have improved properties, in particular in respect of their capacity for transportation of liquids in the swollen state, and which has a high gel bed permeability and high centrifuge retention capacity.
    Type: Application
    Filed: September 1, 2006
    Publication date: March 22, 2007
    Inventors: Scott Smith, Stan McIntosh, Heinz Bremus, Frank Loeker
  • Powdery water-absorbing polymers with fine particles bound by thermoplastic adhesives
    Publication number: 20070066754
    Abstract: A process for producing and a powdery water-absorbing polymers comprising: about 0.01 to 20 wt. % of a fine particle with a particle size of less than about 200 ?m; about 0.001 to 10 wt .% of a thermoplastic adhesive; and about 60 to 99.998 wt .% of a water-absorbing polymer particle with a particle size of about 200 ?m and above, wherein the powdery water-absorbing polymers have: a flow value (FFC) within the range from about 1 to 13, and/or a dust portion of at most about 6 are disclosed. Also disclosed are a transport process, a composite, chemical products, and a use of a thermoplastic adhesive.

  • Method of producing epoxides
    Patent number: 6525209
    Abstract: The present invention relates to the preparation of epoxides by the oxidation of olefins using molecular oxygen with the addition of an aldehyde additive, characterized in that the oxidation is performed in compressed carbon dioxide as the solvent, which, as compared to many conventional organic solvents, is stable towards oxidation, reduces the danger of explosion and is toxicologically and ecologically safe.
