Abstract: High concentration polymer slurries contain up to 65 weight % xanthan gum in a hydrophobic solvent base treated with suspending agents, dispersants, and thinning agents. Mineral oil, diesel oil, kerosene, alcohols (six to twelve carbons), vegetable oil, ester-alcohols, polyol ethers, and the like may be used as the solvent. The preferred suspending agent is either an organophilic clay or hydroxypropyl cellulose. The preferred dispersant is either an ethoxylated linear alcohol or a fatty acid ester of vegetable oil or animal oil. The preferred thinning agent is lecithin. These slurries greatly improve the dispersibility of xanthan gum or any other hydrophilic colloid, such as guar, hydroxypropyl guar, cellulosics, polyacrylamides, and the like.

Abstract: Dispersants, especially well suited for use with insoluble dyes, are produced by reacting hydroxyl benzyl alcohol compounds with sulfonated lignin derivatives. The dispersants have high levels of heat stability, coupled with desirable dye reduction, staining, foaming, milling and viscosity-reducing properties. Dyestuffs, dye pastes and dye baths, as well as methods utilizing them, are provided.

Abstract: Asphalt emulsion conditioner compositions, derived from spent sulfite liquor lignosulfonates, and asphalt emulsions produced from such compositions are provided. The emulsions are of the slow-setting, anionic type and are further characterized by their ability to remain stable on storage although produced with equipment that generates a wide range of shearing forces. Such characteristics are imparted to the asphalt emulsions through the use of emulsion-conditioner compositions comprising a partially desulfonated lignosulfonate, preferably an anionic or nonionic emulsifying agent and, optionally, a thickener.

Abstract: Novel blends of algin, TKP and guar gum are disclosed. The blends are useful in commercial gum applications where thickening, suspending, emulsifying, stabilizing, film-forming, and gel-forming properties are needed. They are particularly useful in the paper industry.

Abstract: Triorganotin compounds of hydroxydiazenium oxides having a good fungicidal action, fungicides containing these compounds, and processes for their manufacture by reacting a triorganotin halide with a sodium or potassium salt of an N'-hydroxydiazenium oxide or with the N'-hydroxydiazenium oxide in the presence of an acid binder.

Abstract: New polythiols-polyesters and corresponding polysulphides in the --SH group wherein sulphur is contained in the alcohol residue after the formation of esters. These polyesters are derived from aliphatic polyacids, saturated or not, wherein the molecule contains a minimum of 15 atoms of carbon. They are formulated by the action of a mercapto-alcanol on the corresponding polyacid, in a liquid which gives an azeotropic mixture with water. These products are useful as additives to asphalts, bituminous products, coatings, mastics and cements.

Abstract: Solution and procedure of depositing a coating on the surfaces of zinc-coated ferrous metal parts which protects against corrosion in the presence of water. The solution is made up by adding to water, perliter of final solution, of 1 to 40 grams of sodium metasilicate, 14 to 40 milliliters of phosphoric acid, specific gravity 1.71, from 1 to 40 grams of sodium nitrate, from 10 to 50 grams of anhydrous zinc chloride and the pH is adjusted to a value between 2.3 and 3.8. Preferably nickel chloride is added. For use, the solution is heated to a temperature ranging from 15.degree. to 75.degree. C and brought into contact with the parts to be treated for a period from 20 to 72 hours. The deposit is continuous, hard, resistant to shocks and abrasion and imparts an efficient and lasting protection to galvanized parts in corrosive waters. The invention is useful for the protection of piping in the building industry.

Abstract: A process of modifying the levelling characteristics of a film of a polar liquid coating composition by incorporating therein 0.5-60% by weight of an amphipathic random copolymer which comprises 5-50% of a monomer which has a chain-like structure at least 80 covalent bonds long and which is soluble in poly(ethylene oxide) of molecular weight 400, and 25-95% of a (meth)acrylate monomer which comprises a chain-like moiety of at least 10 covalent atoms long and which is not soluble in poly(ethylene oxide) of molecular weight 400. The resulting copolymer may be added to polar liquid coating compositions to give useful improvements in flow and levelling characteristics.

Abstract: Aqueous solutions of R zirconium carbonate in which R is selected from ammonium and potassium have a carbonate: zirconium molar ratio not greater than 2.05 and can impart thixotropic properties to aqueous dispersions of polymers and copolymers, such as emulsion paint. The solutions may be prepared by reacting zirconium basic carbonate with ammonium or potassium carbonate solution and have a good storage stability, especially at high concentrations. They may be stabilized further by the addition of an acid selected from tartaric and gluconic acid.
