Abstract: Dry processing of cellulose fibers in an attritor mill produces small cellulose particles with properties useful for increasing the bulk of paperboard products. In contrast with the usual behaviour of small particles, the dry attritor-processed particles exhibit a further benefit of good drainage on a paper machine. Comparisons are made for the modulus, smoothness, and density of paperboard made with and without the dry-attrited cellulose particles.

Abstract: A water-based barrier coating composition is disclosed that has improved barrier performance and enhanced stability. The water-based coating composition comprises a polymeric binder and an amine stabilizer, wherein the pH of the composition is equal to or greater than the pKa of the amine stabilizer. When desired, the disclosed coating composition may further include standard low-cost fillers, layered fillers capable of being at least partially exfoliated, nanoparticle fillers, or mixtures thereof. A multilayer product comprising a layer of the disclosed water-based coating composition is also disclosed that has enhanced oxygen barrier performance.

Abstract: A paperboard containing microplatelet cellulose particles has improved surface smoothness, aesthetic properties, bending stiffness and strength performance. When microplatelet cellulose particles are used for surface treatment of the paperboard, the microplatelets fill voids between fibers on the board surface. As a result, treated board has enhanced strength and surface properties such as smoothness, opacity, coating hold-out, and printability without compromising bending stiffness. Furthermore, the present disclosure relates to a process for improving board strength, surface smoothness and/or bending stiffness without the needs for densification, while maintaining other desired performances.

Abstract: Improvements in the construction of postformable laminates are disclosed by the provision of a single high basis weight sheet exhibiting improved saturation and resin pick up characteristics and formed predominantly of hardwood pulp which pulp has been mechanically treated to effectively impart kinking and curling to the individual pulp fibers.

Abstract: Improvements in the construction of postformable laminates are disclosed by the provision of a single high basis weight, high coarseness, high kappa number sheet formed predominantly of softwood pulp, preferably southern loblolly pine, which pulp has been treated in a mechanical device that effectively imparts kinking and curling to the individual pulp fibers. The sheet is intended as a replacement for the highly extensible sheet(s) currently located on the back of the laminate farthest away from the core.

Abstract: Water-borne alkyd resin compositions are disclosed comprising maleinized fatty acid. Substitution of the aromatic triacid component of the composition with the maleinized fatty acid permits a reduction in the amount of organic cosolvent employed to solubilize the resin in the water. Alkyd resin containing paint formulations also are disclosed.

Abstract: Solvent-borne alkyd resin compositions are disclosed comprising a high-purity maleinized rosin anhydride. Substitution of the trifunctional acid component of the alkyd resin composition with this rosin anhydride permits a reduction in the viscosity of the resin without adversely affecting the physical properties of the cured film of the resin.

Abstract: A process for producing dihalobenzene disulfone compounds, comprising reacting, in the presence of aluminum trichloridea halobenzene sulfonyl halide of the formula ##STR1## wherein X and Y are halogen which may be the same or different, with a compound of the formulaH - Q - Hwherein Q is a divalent radical containing benzenoid unsaturation and the hydrogens are replaceable under electrophilic Friedel-Crafts reaction conditions,in a solvent consisting essentially of about 1 to about 25 volume %, based on the solvent volume, of nitromethane and, correspondingly, about 99 to about 75 volume %, of a polar aliphatic halohydrocarbon, the total solvent volume employed being sufficient to provide between about 0.5 and about 1.

Abstract: Solvent-borne alkyd resin compositions are disclosed comprising a 22-carbon, tall oil fatty acid derived aliphatic anhydride. Substitution of the trifunctional acid component of the alkyd resin composition with a 22-carbon anhydride permits a reduction in the viscosity of the resin without adversely affecting the physical properties of he cured film of the resin.

Abstract: An inhibitor formulation including the product obtained by reacting maleic anhydride or fumaric acid with fatty acids containing unsaturation in the presence of a suitable catalyst, such as iodine, clay, or silica, is disclosed to provide improved corrosion inhibition in oil field equipment and piping over conventional dimer/trimier based inhibitor formulations.
