    Abstract: Ethers of highly polymeric formaldehyde are obtained by reacting the latter with an alphachoralkyl ether of an aliphatic, cycloaliphatic, heterocyclic or aromatic hydroxyl compound, preferably in the presence of a basic compound, or with a quaternary salt of the alpha-chloralkyl ether with a tertiary amine. Alpha-chloralkyl ethers mentioned are chlormethyl methyl ether, chlormethyl ethyl ether, bis-(chlormethyl) ethylene glycol ether, bis-(chlormethyl) butane-diol-(1,4) ether, chlormethyl cyclohexyl ether, chlormethyl benzyl ether and chlormethyl cyclohexyl ether. In Examples polyformaldehyde is reacted with quaternary salts of dimethylcyclohexylamine with chlormethyl methyl ether, 1,4-bis (chlormethoxy) butane, alpha-chlorethyl isobutyl ether, alpha-chlorethyl benzyl ether and 2,3-dichlordioxane.

    Abstract: A composition suitable for treating cellulosic fabrics comprises a compound which improves the crease resistance of the fabric and a copolymer of 1-10% by weight of a N-methylolamide of an acrylic acid and 0.5-10% by weight of at least one compound containing in the molecule at least two polymerizable double bonds, the balance of 100% by weight being made up of at least one further polymerizable compound. The N-methylolamide of an acrylic acid may be N-methylolacrylamide or N-methylolmethacrylamide or an ether derivative thereof and suitable compounds containing at least two double bonds are divinyl benzene and its derivatives and substitution products, ethylene glycol diacrylate, butane diol diacrylate or dimethacrylate, hexane diol diacrylate, glycerol triacrylate, vinyl methacrylate, 1,3,5 - triacyl - hexahydrotriazine - (1,3,5) allyl acrylate and methylene bisacrylamide. The further polymerizable compounds making up the copolymer may be methyl, ethyl, propyl or butyl acrylate or methacrylate, acrylonitrile, isopropyl acrylate, N-dibutylacrylamide, ethylhexyl acrylate or vinyl-pyrrolidone. The crease proofing agent may be a methylol compound of urea, ethylene or propylene urea, diphenyl urea, methyl urea, thiourea, dicyandiamide, guanidine, melamine, methylmelamine, phenyl melamine, glyoxal monoureine or diureine, a urethane, polyurethane, lactam, polyamide, triazinone, carboxylic amide or diamide or ether thereof, a methylol compound of a ketone, an acetal, an epoxy compound or a water soluble polymer or copolymer of an amide of an unsaturated carboxylic acid. The composition may be in the form of an aqueous solution or dispersion containing 30-150 g./l. of the crease-resisting agent and 5-100 g./l. of the copolymer and if desired an organic liquid, e.g. ethyl alcohol or glycerol, softeners, water repellants, colouring pigments and an acid condensation catalyst, e.g. magnesium chloride, zinc nitrate, mono-ammonium phosphate, ammonium nitrate and ammonium acetate. ALSO: The tendency of crease proofed cellulosic fabrics to become irreversibly soiled during washing with hot aqueous liquids is reduced by effecting the crease-proofing by a process comprising treating them with a compound which improves the crease resistance of the fabric and with a copolymer of 1-10% by weight of a N-methylolamide of an acrylic acid and 0.5-10% by weight of at least one compound containing in the molecule at least two polymerizable double bonds, the balance of 100% by weight being made up of at least one further polymerizable compound. The N-methylolamide of an acrylic acid may be N-methylolacrylamide or N-methylolmethacrylamide and suitable compounds containing at least two double bonds are divinyl benzene and its derivatives and substitution products, ethylene glycol diacrylate, butane, diol diacrylate or dimethacrylate, hexane diol diacrylate, glycerol triacrylate, vinyl methacrylate, 1,3,5- triacryl-hexahydrotriazine- (1, 3, 5) allylacrylate and methylene bisacrylamide. The further polymerizable compounds making up the copolymer may be methyl, ethyl, propyl or butyl acrylate or methacrylate, acrylonitrile, isopropyl acrylate, N-dibutylacrylamide, ethylhexyl acrylate or vinylpyrrolidone. The crease proofing agent may be a methylol compound of urea, ethylene or propylene urea, diphenyl urea, methyl urea, thiourea, dicyandiamide, guanidine, melamine, methylmelamine, phenyl melamine, glyoxal monoureine or diurein, a urethane, polyurethane, lactam, polyamide, triazinone, carboxylic amide or diamide or ether thereof, a methylol compound of a ketone, an acetol, an epoxy compound or a water soluble polymer or copolymer of an amide of an unsaturated carboxylic acid. The crease resisting agent and copolymer may be applied from an aqueous solution or dispersion containing 30-150 g/1 of the crease resisting agent and 5-100 g/1 of the copolymer and if desired an organic liquid, e.g. ethyl alcohol or glycerol, softeners, water repellants or colouring pigments. Alternatively the crease resisting agent and the copolymer may be applied successively in any sequence. The treating agents may be fixed on the fabrics by the action of an elevated temperature and/or an acid condensation catalyst, e.g. magnesium chloride, zinc nitrate, monoammonium phosphate ammonium nitrate and ammonium acetate. After impregnation and prior to heating the fabric may be calendered on a Schreiner calender. Fabrics comprising cotton, linen, or viscose rayon fibres alone or in admixture with polyamide, polyester, cellulose ester or acrylonitrile polymer fibres may be treated.

    Abstract: 939,097. Coated fabrics. BADISCHE ANILIN- & SODA-FABRIK A.G. Dec. 6, 1961 [Dec. 7, 1960], No. 43649/61. Class 140. Fabrics, especially fabrics of man-made fibres, such as a polycaprolactam fabric, are coated by the application thereto of a solution in a volatile solvent of (a) at least one copolymer of a mixture of (i) at least one unsaturated polymerizable compound containing one or more hydroxyl groups, and (ii) at least one other unsaturated polymerizable compound and (b) at least one polyisocyanate, the solvent is evaporated and the copolymer and polyisocyanate are cross-linked by heating. At least one of the unsaturated polymerizable compounds (i) may be a polymerizable ester of a carboxylic acid which still contains a hydroxyl group, e.g. a partial ester of acrylic or methacrylic acid with a polyhydric alcohol, such as partial esters of butane-1,4-diol-monoacrylate, pentane - 1,4 - diol - monoacrylate and ethylene glycol monomethacrylate. Especially suitable components for copolymerization with these partial esters are acrylic and methacrylic acid esters of alcohols with 1 to 4 carbon atoms, e.g. butyl acrylate, methyl methacrylate, or vinyl esters, e.g. vinyl acetate or propionate. Component (a) may be prepared by polymerization of monomer mixtures containing 0.5 to 10% of monomer (i). The proportion of component (b) may be 0.5 to 10% by weight of component (a). Polyisocyanates specified are the reaction products of polyhydric alcohols with toluylene polyisocyanates which have an excess of reactive isocyanate groups, and di-isocyanates such as hexamethylene-, 1,4-phenylene-, toluylene- or naphthalene-1,5-di-isocyanates. Heating may be carried out at a temperature between 60‹ and 160‹ C., especially between 90‹ and 150‹ C. The solution used for coating may have a solids content between 30 and 70%. A second coating of different composition, e.g. a silicone resin or a modified urea resin, may be applied to the first coating.
