  • Patent number: 9718974
    Abstract: The invention relates to low-viscosity formulations of radiation-curable compounds, to processes for preparing them, to their use, and to inks, printing-inks, and print varnishes that comprise them.
    Type: Grant
    Filed: January 28, 2016
    Date of Patent: August 1, 2017
    Assignee: BASF SE
    Inventors: Juergen Kaczun, Reinhold Schwalm, David Trumbo, Eugene Valentine Sitzmann
  • Publication number: 20160258868
    Abstract: A polyurethane foam includes a fluorescent repeating unit. The authenticity of a polyurethane foam may be determined by irradiating the foam with a UV light and determining if there is a fluorescent emission.
    Type: Application

  • Patent number: 9394244
    Abstract: Disclosed are functional polyallophanate oligomers comprising ethylenically unsaturated groups and polymer stabilizer groups selected from hindered amine light stabilizers, ultraviolet light absorbers, antioxidants and dihydrocarbylhydroxylamines. The ethylenically unsaturated groups and the polymer stabilizer groups are bound to the polyallophanate oligomers through allophanate and/or carbamate groups. The polyallophanate oligomers are useful in curable coatings, inks and varnishes. The present polyallophanate oligomers are derived from a) organic polyisocyanates, b) compounds containing at least one isocyanate reactive group and at least one ethylenically unsaturated group and c) polymer stabilizers containing at least one isocyanate reactive group.

  • Publication number: 20160017094
    Abstract: A process for preparing a polyoxazoline includes feeding continuously an oxazoline, a solvent, and a catalyst to a continuous stirred tank reactor at a rate which provides for a residence time sufficient to achieve ring opening of the oxazoline and polymerize the oxazoline; exiting a polyoxazoline solution from the continuous stirred reactor, the polyoxazoline solution including polyoxazoline, solvent, and, optionally, unreacted oxazoline, low molecular weight oligomeric oxazoline, or a mixture thereof; removing the solvent, and, optionally, unreacted oxazoline, low molecular weight oligomeric oxazoline, or a mixture thereof from the polyoxazoline solution; and recovering the polyoxazoline.
