    Abstract: Emulsion copolymers obtainable by copolymerization in the emulsion of (a) a dye which contains a polymerizable olefinic double bond, (b) one or more non-coloured compounds which contain polymerizable olefinic double bonds and groups accessible to cross-linking by addition or condensation and, optionally, (c) one or more polymerizable non-coloured compounds (inert to cross-linking) used for the production of plastics are employed for simultaneously dyeing and finishing textiles and are subsequently cross-linked either alone or with the aid of (d) suitable bi- or polyfunctional compounds, either by condensation or addition. The chromophoric monomers (a) may be based on dyes of the azo, anthraquinone, triarylmethane, phthalocyanine, phenazine and oxazine series (see Group IV(c)). While many components (b) and (c) are specified those mentioned in the examples are (b) N-methylolmethacrylamide, N-methylol-acryloylurea, N-methylol-N-acryloylmaleic acid imide, butanediol monoacrylate, methacrylamide, acrylic acid and 2:4-diamino-6-acryloylaminoethylene-1:3:5-triazine and (c) ethyl acrylate, butyl acrylate, methyl methacrylate, acrylonitrile, styrene, vinyl propionate and vinyl chloride. The copolymers, whose solid content is preferably 25-50%, may be prepared in the presence of polymerization initiators such as hydrogen peroxide and potassium persulphate. Cross-linking may be effected by heating or changing the pH with or without the aid of many specified components (d) and other catalysts. The components (d) mentioned in the examples are the bisulphite compounds of hexamethylene di-isocyanate and toluylene di-isocyanate, N,N1-dimethylolurea and its methyl ethers, the N,N1-dimethylolated diurethane of butane-diol-(1,4), the reaction product of pentaerythritol and epichlorhydrin and an etherified urea-formaldehyde resin precondensate. Examples are given of the preparation of copolymers and their employment in dyeing and printing fabrics.ALSO:Textiles are simultaneously dyed and finished by treating with emulsion copolymers obtainable by copolymerization in the emulsion of (a) a dye which contains a polymerizable olefinic double bond, (b) one or more non-coloured compounds which contain polymerizable olefinic double bonds and groups accessible to cross-linking by addition or condensation and, optionally, (c) one or more polymerizable non-coloured compounds (inert to cross-linking) used for the production of plastics, and subsequently crosslinking the copolymer either alone or with the aid of (d) suitable bi- or polyfunctional compounds, either by condensation or addition. The chromophoric monomers (a) may be based on dyes of the azo, anthraquinone, triarylmethane, phthalocyanine, phenazine and oxazine series; suitable dyes are described in Specifications 830,876, 858,183, 875,946, 877,402 and 879,071, German Specification 1,010,063 and French Specification 1,118,705. Many components (b) are specified, among which are N-methylolmethacrylamide, N-methylol-N-acryloylmaleic acid imide, butanediol monoacrylate, methacrylamide and acrylic acid; many components (c) are also specified, those mentioned in the examples being ethyl acrylate, butyl acrylate, methyl methacrylate, acrylonitrile, styrene, vinyl propionate and vinyl chloride. The copolymer emulsions, whose solid content is preferably 25-50%, may also contain the usual emulsifiers and protective colloids, as well as a thickener, when the copolymer is used as a printing paste. Cross-linking may be effected by heating or changing the pH with or without the aid of many specified components (d) and other catalysts. Examples are given of the preparation of copolymers and the dyeing and printing of fabrics of cotton (woven and non-woven), rayon staple, calico and regenerated cellulose. Other specified materials are of wool, silk, polyamide, cellulose acetate, polyvinyl alcohol and polymers and copolymers of acrylonitrile.

    Abstract: Quaternary ammonium salts of vinyl sulphonic acid (0,1 to 10%) may be copolymerized with 99,9-90% of other ethylenically unsaturated polymerizable compounds in aqueous dispersion free from emulsifier and in otherwise conventional manner. Examples specify the polymerization of trimethylphenylammonium vinyl sulphonate, trimethylcyclohexyl ammonium vinyl sulphonate, the quaternary ammonium salts prepared by reacting triethanolamine and methyl vinyl sulphonate and reacting methyl vinyl sulphonate with the reaction product of 1 mol. of diethylamine and 4 mols. of ethylene oxide. The other unsaturated monomers may be vinyl acetate, vinyl propionate, ethyl acrylate, n-butyl acrylate or vinylidene chloride. The initiator system may be potassium persulphate or potassium persulphate/sodium pyrophosphate. Many other monomers and initiator systems are mentioned.

    Abstract: 880,993. Agglutinated fibrous fabrics; impregnated paper &c. BADISCHE ANILIN- & SODA-FABRIK A.G. Oct. 30, 1959 [Nov. 5, 1958], No. 36863/59. Classes 96 and 140. A process for the production of a bonded fibre fleece comprises employing as a binder a copolymer derived from 1 to 20% by weight of an alpha-beta unsaturated carboxylic acid amide substituted on nitrogen by at least one methylol group, and 80 to 99% by weight of at least one other polymerizable compound, the fleece containing the binder being heated for a short time, e.g. 3 to 10 minutes, at over 60‹ C. Fibrous materials mentioned are cotton, rayon, cellulose acetate, wool, sisal, polyamides, polyvinyl chloride, polyacrylonitrile, polyterephthalic acid esters, rock wool, slag wool, glass fibres and asbestos fibres, and the polymerizable compound may be an ethylenically unsaturated monomer, e.g. acrylic and methacrylic acid esters, e.g. butyl acrylate, vinyl esters and ethers, styrene, acrylonitrile, and olefines, or mixtures thereof. The methylol compound may be N-methylolamide of acrylic, methacrylic or maleic acid. The binder may be applied as an aqueous emulsion or dispersion, or dissolved in an organic solvent, or strewn in the solid state on the fleece. If the binder is in liquid form, the heating operation may be in two stages, the first at 60‹ C. to 100‹ C., the second at 80‹ C. to 160‹ C. The fleece, prior to impregnating, may be formed by carding, and may be laminated so that the fibres in successive layers lie at an angle to each other, or a random arrangement of fibres may be employed, e.g. by suspending in water which is sucked off on a sieve. Impregnation may be carried out by spraying or soaking, and the liquid may be supplied between two fleeces as they are passed between two rollers under light pressure the fleeces having undergone a preliminary consolidation prior to impregnation. Compounds may be added to the binder to accelerate the reaction, e.g. phosphoric acid, paratoluenesulphonic acid, acetic acid, AlCl 3 , NH 4 NO 3 , NH 4 Cl, and ammonium oxalate, and soluble dyestuffs, colour pigments, plasticizers, stabilizers and optical brightening agents may be added to the binder. Four examples are described in detail and one describes the passing of the impregnated fleece through a bath consisting of melamine-urea precondensate and ammonium oxalate.
