The present application discloses improved lignocellulosic composite materials comprising a lignocellulosic component, a bis-electrophile, and a polynucleophile. Exemplary embodiments comprise a dianhydride and a polyol.

Lignocellulosic composites and methods of making same

Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines. Crystallization suppressant blends are also identified that allow for the preparation of high density clear brine fluids with lower viscosities.

Crystallization suppressant combinations for high density clear brine fluids

The present invention provides compositions comprising the reaction product of an aliphatic diisocyanate, and a reactive intermediate made from one selected from the group consisting of oxazolidinones, benzoic sulfimides (saccharins), 1H-indole-2,3-diones (isatins), succinamides, N-hydroxysuccinamides, 4-hydroxy-3-methoxybenzaldehydes (vanillins), &#x3b1;-ketoamides, piperazines, benzofuranones, 3,4-dihydroxycyclobut-3-ene-1,2-diones (squaric acids), squaric acid esters, &#x3b1;-ketoamides, anilines, and &#x3b1;-ketoamide, phenols. The aliphatic diisocyanate comprises one selected from the group consisting of isocyanurates, biurets, iminooxadiazine diones, urethanes, uretdiones, carbodiimides, and allophanates. The resulting compositions may be useful in producing coatings, adhesives, sealants, castings, composites and films having durability, color stability, high gloss, and chemical resistance properties similar to those made from polyurethane.

Alternative crosslinking mechanisms for polyurethane-based systems

Compounds are identified that act as crystallization suppressants when added to clear brine fluids, significantly lowering the true crystallization temperatures of the brines, and allowing for higher salt content in clear brine fluids. The crystallization suppressants of the invention also allow for the preparation of higher density zinc free brines.

High densitiy clear brine fluids

A thermal recording material having a heat-sensitive color-forming layer that contains a phosphate modifier in addition to an activator and lueco dye can provide good imaging. The phosphate modifier such as unsubstituted dibenzyl phosphate can be paired with an activator such 3-(4-hydroxyphenyl)propionic acid to provide an environmentally friendly thermal recording material.
