    Abstract: 1,143,067. Coated glass fibrous materials. BADISCHE ANILIN-& SODA-FABRIK A.G. 22 March, 1967 [23 March, 1966; 12 Jan., 1967], No. 13420/67. Heading B2E. [Also in Division D1] Glass fibres and articles formed therefrom e.g. woven and nonwoven fabrics are finished by impregnating with an aqueous liquor which contains at least one film forming high molecular weight substance and, if desired, one or more finely divided pigment and/or conventional additives, and drying the impregnated material, wherein the material is impregnated with aqueous hydrofluoric acid before, during or after the treatment and then dried at a temperature of at least 50‹C. The fibrous material may be first impregnated with an aqueous liquor which contains hydrofluoric acid and at least one film forming high molecular weight substance, and the material then dried at a temperature of at least 50‹C; the impregnated material may be subsequently treated with film forming high molecular weight substances and, if desired, pigment and/or conventional additives. The hydrofluoric acid may be applied at the rate of 0.01-3%, and the film forming high molecular weight substance may be applied in a total amount of 0.05-10%, calculated as anhydrous pure substance and based on the weight of the fibrous material. After drying the fibrous material may be mechanically pressed or bent, or may be callendered at a lineal pressure of 10-60 kg/cm. The high molecular weight substance may be synthetic or naturally occurring and has a molecular weight of at least 10,000; examples are given.

    Abstract: The pile of pile fabrics, e.g. carpets, velvet, plush, cord and velveteen, derived for example from natural or regenerated cellulose fibres, wool, silk, cellulose ester, polyamide, polyester and acrylonitrile polymer fibres, is secured by treating the reverse side of the fabrics with dispersions of copolymers derived from 1-25% by weight of an N-methylolamide of an acrylic acid that may be etherified and 99-75% by weight of one or more other polymerizable compounds and subjecting the fabrics to a heat treatment at a temperature above 100 DEG C. In addition to the N-methylolamide of an acrylic acid or ether thereof the copolymer may also comprise other unsaturated carboxylic acid amides, derivatives of these carboxylic amides which are mono substituted at the nitrogen atom and the methylol compounds of these amides, esters, nitriles and N-disubstituted amides of unsaturated carboxylic acids, vinyl esters, halides, cyanides, ethers, ketones and aromatics, vinylidene halides and cyanides, C-vinyl pyridine, N-vinyl compounds, e.g. N-vinyl imidazole, N-vinyl pyrrolidone, N-vinyl caprolactam and N-vinyl pyridine, unsaturated aldehydes and esters of unsaturated alcohols, e.g. allyl and methallyl alcohols. The fabrics may be treated on the reverse side with aqueous dispersions of the copolymers having a concentration of 3-50% with reference to the weight of the liquor by coating or padding, dried at temperatures up to 100 DEG C. and then heat treated at temperatures above 100 DEG C. The dispersions may also contain thickeners, e.g. starch, cellulose and starch ethers, polyacrylic acids and their salts and salts of copolymers derived from acrylonitrile and acrylic acid, resin forming substances, e.g. tetramethylol acetone, dimethylol acetal, dimethylol urea, trimethylol melamine, dimethylol ethylene urea, dimethylol glyoxal monoureine, dimethylol butane diol diurethane, dimethylol adipamide, dimethylol propylene urea, dimethylol alkyl triazones and ethers thereof and polyfunctional epoxy compounds such as glycol and diglycol diglycidyl ethers, in combination with hardening catalysts, organic and inorganic fillers and pigments, polyacrylamides, polyvinyl ethers, polyvinyl esters, polyvinyl alcohol, clay, kaolin, china clay, barium sulphate, calcium carbonate, titanium dioxide, zinc oxide, iron oxide, chromium oxide and substative dyes. The treatment may be carried out in conjunction with a padding impregnation with a water repellant comprising a metal salt/paraffin emulsion or silicone.

    Abstract: An ethylenically unsaturated polyester is prepared by passing substantially stoichiometric amounts of (a) at least one dibasic carboxylic acid or anhydride, of which at least a part is unsaturated, (b) at least one dihydric alcohol and optionally (c) minor amounts of (c1) mono- or tri- or higher carboxylic acids and/or (c2) mono- or tri- or higher hydric alcohols, and/or (c3) hydroxy-carboxylic acids, continuously through 3 or 4 stirred vessels in series, the temperatures of the first and last vessels being 120-190 DEG C. and 195-240 DEG C. respectively, the temperature(s) of the intermediate vessel(s) being higher than that of the first vessel and below that of the last. The pressure in the last 1 or 2 vessel(s) is preferably 20-200 mm. Hg., in the first 500-900 mm. Hg. The mean residence time in each vessel is preferably 1-7 hours, and each vessel is preferably 70-80% full of reaction material, an inert gas occupying the remaining volume. Suitable starting materials are (a) maleic, fumaric, o-, m- and p-phthalic, and 1,2,3,6-tetrahydrophthalic acids, 3,6 - endomethylene - 1,2,3,6 - tetrahydrophthalic acid, succinic, adipic, and sebacic acids or anhydrides, (b) ethylene and propylene glycols, trimethylene-, tetramethylene- and hexamethylene glycols, neopentyl glycol, and 2,2,4 - trimethylpentanediol - 1,4, (c1) benzoic, trimellitic, pyromellitic acids, (c2) octanol, decanol, glycerol, pentaerythritol, and (c3) 3-methylol-cyclohexane carboxylic acid. In an example, maleic and phthalic anhydrides are condensed with propylene glycol in three vessels.

    Abstract: (1,3)-Diene homo-or co-polymers are modified (a) by isomerization, e.g. by heating alone or in solution with transition metals of Group VI to VIII of the Periodic Table and/or compounds which contain these transition metals in zerovalent form, or (b) by heating alone or in solution with a -ethylenically unsaturated carboxylic compounds and/or derivatives of such compounds. The (1,3)-diene homopolymer may be a homopolymer of a C4- 12 (1,3)-diene, e.g. buta - (1,3) - diene, 2 - methylbuta - (1,3)- diene, cyclopenta - (1,3) - diene, or cyclohexa - (1,3) - diene. The (1,3) - diene copolymer may be derived from a (1,3)-diene and ethylene, propylene, 2-methyl-1-butene, an ester of an acrylic or methacrylic acid with a C1- 6 alkanol, acrylonitrile, styrene, a -, o-, m-, or p-methylstyrene, or a mixture thereof. Specified transition metals and compounds thereof are Fe, Co, Ni, Mn, Cr, Mo, W, Pd, Pt, Ni(CO)4, Fe (CO)5, HCo(CO4, [Co(CO)4]2, H2Fe(CO)4, Fe2(CO)9, Fe3(CO)12, nickel-(o)-bis-cycloocta-(1,5)-diene, and Mn2(CO)2. Specified a -ethylenically unsaturated carboxylic compounds and derivatives thereof are maleic anhydride, maleic acid, fumaric acid, acrylic acid, methacrylic acid, and esters of the acids with C1- 6 alkanols. The (1,3)-diene polymers, and their modified derivatives, are oxidized by treatment either alone or in solution with an oxygen transferring agent, e.g. oxygen, organic peroxides, or conventional driers, e.g. Fe, Co, Pb, Mn naphthenates, caprylates, or oleates, to form polymers having peroxidic oxygen atoms. The treated polymers may be mixed with wood flour, cork powder, or powdered fillers.ALSO:Coated sheet material which may be used as floor, table, or wall covering is prepared by applying a mixture of 15 to 60% by wt, of an oxidised (1,3)-diene polymer and 40 to 85% by wt. of wood, flour, cork powder and/or stone powder to a woven or non-woven web of natural and/or artificial fibres, and pressing the coated web at a temperature of from 50 -200 DEG C. The (1,3)-diene polymer may be a homopolymer e.g. of buta-(1,3)-diene, 2-methyl buta-(1,3)-diene, cyclopenta-(1,3)-diene, cyclohexa-(1,3)-diene, or a co-polymer of a -(1,3)-diene with, for example, ethylene, propylene, 2-methyl-1-butene, an ester of acrylic or methacrylic acid with a C1-6 alkanol, acrylonitrile, styrene, a -methylstyrene, o, m, or pmethylstyrene, or a mixture thereof. The homo- or copolymer may be modified, prior to oxidation either by isomerisation e.g. by heating alone or in solution in the presence of Group VI to Group VIII transition metals and/or compounds which contain these transition metals in zerovalent form; or by reaction with a -ethylenically unsaturated carboxylic compounds and/or derivatives of such compounds e.g. mallic anhydride, mallic acid, fumaric acid, acrylic acid, methacrylic acid, and esters thereof with C1-6 alkanols. Oxidation may be carried out using oxygen and/or oxygen donors e.g. organic peroxides and driers e.g. Co, Fe, Pb, and Mn naphthenates, caprylates and oleates. The organic peroxides and/or driers may be added to the oxidised polymers or mixtures thereof with wood flour, cork powder and/or stone powder, optionally with natural or synthetic resinse.g. linoxyn, linseed oil varnish, colophony, kauri gum, wood oil, and other conventional auxiliaries e.g. pigments. The web is preferably made of jute but may also be of wool, hemp, sisal, cellulose, acetylcellulose, polyamide, polyester, polyacrylonitrile, polyethylene, polypropylene, glass or mineral fibres.
