  • Uv-active binding agent
    Publication number: 20060148975
    Abstract: The present invention relates to processes for preparing actinic-radiation-curable and/or dual-cure poly(meth)acrylates by preparing a poly(meth)acrylate containing hydroxy-functional side chains and transesterifying or esterifying the poly(meth)acrylate containing hydroxy-functional side chains with a (meth)acrylate or (meth)acrylic acid. The present invention further relates to the actinic-radiation-curable and/or dual-cure poly(meth)acrylates themselves and to the use of the actinic-radiation-curable and/or dual-cure poly(meth)acrylates in the preparation of dispersions or as a component in coating formulations and topcoats comprising at least one actinic-radiation-curable and/or dual-cure poly(meth)acrylate.

  • Coating composition and its use and process for its preparation
    Patent number: 6274660
    Abstract: The present invention relates to a coating composition featuring increased solids contents, which comprises at least one polyol I obtainable by subjecting at least one oligomer of the general formula I R1R2C═[═CH—R—CH═]n—CR3R4  (I) in which R=—(—CH2—)m—, in which the index m is an integer from 2 to 6, or in which X=—CH2— or an oxygen atom R1,R2,R3 and R4 independently of one another=hydrogen atoms or alkyl; and the index n=an integer from 1 to 15; to hydroformylation and reducing the resultant aldehyde-functional products I to give the polyols I, which, if desired, are subjected to partial or complete hydrogenation.

  • Process for the elimination of hydrogen sulfide or iron sulfide from an aqueous system
    Patent number: 4501668
    Abstract: There are employed water soluble low molecular weight polycondensation products produced by the condensation of acrolein and formaldehyde in a molar ratio between 1:1 and 1:10 in aqueous or aqueous-organic medium in the presence of a basic catalyst for the elimination of hydrogen sulfide and iron sulfide present in aqueous systems. The condensation reaction can also be carried out in the additional presence of water soluble monohydric or polyhydric alcohols and/or acid amides.

    Date of Patent: February 26, 1985
    Assignee: Degussa Aktiengesellschaft
    Inventors: Wolfgang Merk, Karl-Heinz Rink
  • Use of polycondensation products from acrolein and formaldehyde as biocide
    Patent number: 4479820
    Abstract: There are employed as biocides for aqueous systems water soluble low molecular weight polycondensation products which are produced from acrolein and formaldehyde in the molar ratio between 1:1 and 1:10 in aqueous or aqueous-organic medium in the presence of a basic catalyst. The condensation reaction can also be carried out in the additional presence of water soluble mono- or polyhydric alcohols and/or acid amides.
