Abstract: 26,928. Lilienfeld, L. Nov. 19. Coating materials and compositions; impregnating-compositions. - Sulphur derivatives of alcohols and hydrocarbons are used for the manufacture of waterproof materials, waxed cloth, and substitutes therefor, and for oilcloth, artificial leather, linoleum and other floor coverings, waterproof and transparent paper, lincrusta, waterproof carpets, bed linings, tracing cloth, and book-binding cloth. The sulphur derivatives used are mercaptans, sulphides and polysulphides of hydrocarbons and alcohols, as well as their anhydrides, and of their polymerides, also the mercaptides, ethers, esters, mercaptols, mercaptals, sulphinic acids, sulphonic acids, sulphoxides, and sulphones derived from these sulphur compounds. Particularly suitable are the sulphur derivatives of propane, propylene, cyclopropane, and glycerine, such as the thioglycerine produced by the reaction of mono- and di-chlorhydrins with inorganic sulphides, the mono-, di-, and tri-thiopyroglycides produced therefrom by polymerization, the compounds produced by the action of metal sulphides upon di-chlorhydrins, the polymerization products of these compounds, and the compounds produced by the action of thiocarbonates, including viscose, upon alkyl halides, halogenhydrins; or other esters, such as glycerine, trithiocarbonic acid. The sulphur derivatives may be produced in the particular product or in the mass from which this product is to be made, either by adding to the mass those bodies from which the sulphur derivatives is to be made by chemical reaction, or by adding any one of such bodies and treating the product with the other. The sulphur derivatives may be mixed with other bodies in order to obtain useful products, for example with cellulose &c., crude or purified viscose, nitrocellulose, acetylcellulose, albumenoids, proteids, glue, amyloid, starch and substances resembling starch such as inulin, levulin, lichenin, &c., dextrin, gum, cerasin, tragacanth, beetroot gum, vegetable gums such as agar-agar, galactan, pectin, pectinuous substances, tragasol, resins, the resinous products of condensation of phenols with aldehydes or aromatic amines, shellac, oxidized and non-oxidized drying oils, caoutchouc, gutta-percha, balata, caoutchouc, surrogates, reclaimed rubber, metal resinates, fatty acid salts, waxes, paraffin, soaps, fats, &c. In examples, woollen, linen, cotton, or silk fabric or fibre, or paper, is treated with a thioglycerine or oxytrimethylenesulphide alone, or with a solvent or mixed with China clay, zinc white, or other loading material, and left to itself or heated until the transformation product has attained the desired consistence; glue, starch, syrup, and a thioglycerine or oxytrimethylenesulphide are mixed and fibres, fabrics, or paper treated with this finishing material, with or without treatment with formaldehyde, bichromate, alum, &c., and heated or not as desired; fibre, fabric, or paper is treated with a mixture of viscose, thioglycerine, or oxytrimethylenesulphide ; fabric is treated with a sulphur derivative as above and heated; viscose mixed with a sulphur derivative, a lake or other pigment, and with or without another softening agent and other substances, is coated in one or several layers upon fabric, paper, &c., and dried, . heated, passed through suitable baths, again dried and further treated by calendering, goffering, pressing, etc.; glue mixed with a sulphur derivative, and with or without colouring- matter, is applied to fabrics &c., and with or without treatment to render the glue insoluble.
