Abstract: Fungicidal solutions containing 2,4,5,6-tetrachloroisophthalodinitrile are provided. The solutions are prepared by dissolving from 5% to 12% by weight of 2,4,5,6-tetrachloroisophthalodinitrile in 1,3-dimethyl-2-imidazolidinone. The solutions are clear and can be stirred without streaking or sedimentation into water-based paints or lacquers or solvent-containing paints or lacquers.

Abstract: A process for the alkaline refining of gum splits is provided. Also provided are hydraulic fluid fracturing compositions which contain alkaline refined gum and which exhibit superior solution viscosity and low residue after break. Also provided is a method of hydraulic fluid fracturing of the subterranean formations surrounding a well using such compositions.

Abstract: A thickener composition is comprised of a polymer having as the major recurring structural unit an acrylamidoalkanesulfonic acid or derivative thereof and a polyvalent metal crosslinking agent is provided. The compositions are useful for thickening aqueous solutions within a specified range of pH. The thickener is effective even in aqueous compositions having high levels of electrolytes.

Abstract: A composition of matter useful as a high solids coating is disclosed. The composition contains at least one fatty polyol derived by ring-opening an epoxidized fatty alcohol or ester, and at least one methylolamino curing agent. The coatings from these compositions have increased flexibility as compared to coatings prepared from comparable polyols.

Abstract: Fatty ethers are provided which are lower alkyl ethers cyano-substituted lower alkyl ethers, ester ethers or amide ethers of fatty alcohols substituted with at least one of the following substituents: formyl, methylol, or acryloxymethyl. The substituted fatty ethers are useful as monomers in a wide variety of polymer systems.
