  • Publication number: 20150176211
    Abstract: Certain embodiments described herein are directed articles that include a cellulosic substrate (or a non-cellulosic substrate) and an aqueous dispersion disposed on the substrate. In certain examples, the dispersion is effective to provide a water vapor perm rating of about 2 perms or less at 25% average RH as tested by ASTM D1653, or about 2 perm or less at 25% average RH as tested by ASTM E96, when the dispersion is cured as a coating on the substrate. In some embodiments, the substrate can be (or can be part of) a building substrate such as, for example, kraft paper placed on insulation (e.g., fiberglass insulation) or oriented strand board. In some instances, the aqueous dispersion can include a plant oil macromonomer or a waterborne epoxy resin.

  • Patent number: 8680176
    Abstract: The present invention provides a nanocapsule of a blocked isocyanate encapsulated within a polymeric nanosphere. In one aspect, the polymeric nanosphere is functionalized. Free isocyanate functionality is released upon thermal annealing or UV exposure of the nanospheres containing the blocked isocyanate. This present invention also provides a novel method for encapsulating isocyanates in aqueous media. In one aspect, the method comprises miniemulsion polymerization. The thermally or UV deblocked isocyanate can be used as an active functional group for many potential applications.

  • Patent number: 8450414
    Abstract: The present invention is directed to a fatty amide (meth)acrylate monomer, methods of making the monomer, and latex polymers comprising the fatty amide (meth)acrylate monomer. The monomers are derived by reacting unsaturated vegetable oils with ethanolamine or substituted ethanolamine. The vegetable oil derivative is then reacted with either (meth)acryloyl chloride or (meth)acrylic acid to form a fatty amide (meth)acrylate monomer or the product of the reaction of hydroxyethyl (meth)acrylate reacted with isophorone diisocyanate to form a urethane fatty amide (meth)acrylate monomer. The increased hydrophilicity of the fatty amide (meth)acrylate monomer facilitates the diffusion through the aqueous phase. The monomer synthesis is designed to be glycerol ester-free to increase long term stability for monomers and polymers.
