Abstract: Oil and grease resistant paper products are disclosed that include a substrate and, on at least one side of the substrate, a continuous layer of a barrier coating, the barrier coating comprising a binder system and a pigment. The barrier coating, when applied to the substrate and dried to form a barrier layer, has a Pigment Volume Concentration (PVC) that is below a Critical Pigment Volume Concentration (CPVC) of the barrier coating, providing a continuous three-dimensional film of the binder system. In some implementations the binder system comprising a latex and a natural binder and/or the paper product further includes a topcoat disposed on a side of the barrier coating opposite the substrate.

Abstract: Coating compositions, including high degree of substitution (DS), viscosity optimized starches, are disclosed for use in non-barrier paper coatings. Paper coated with the same is disclosed as well as methods of making the coating compositions and coated papers.

Abstract: Degraded hydroxyalkylated starches and methods of preparing the same from waxy, normal, or modified starches are provided. The starches can be prepared by several approaches that involve acid or enzyme degrading either before or after starch modification with an alkylene oxide. The modified and degraded starches exhibit improved swelling characteristics, solution stability of cooked starch, improved film-forming properties and/or improved coating performance. In addition, the degraded hydroxyalkylated starches can be used as a fat replacement in foods, in film-forming compositions, in coating compositions, and to encapsulate other materials.

Abstract: The present invention relates to urea-functionalized crystalline capsules self-assembled by sodium or potassium cation coordination and by hydrogen-bonding water bridges to selectively encapsulate tetrahedral divalent oxoanions from highly competitive aqueous alkaline solutions and methods using this system for selective anion separations from industrial solutions. The method involves competitive crystallizations using a tripodal tris(urea) functionalized ligand and, in particular, provides a viable approach to sulfate separation from nuclear wastes.
