    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: Ethylene copolymer dispersions with a high solids content and a good freeze-thaw stability are prepd. by the aq. emulsion polymsn. of ethylene and an unsatd. comonomer contg. oxygen and/or sulphur in an amount giving a copolymer contg. 2.0 - 4.0 wt.% oxygen and/or 0.5 - 1.0 wt.% sulphur, in the presence of a free radial initiator, and of 2 - 20 wt.%, based on aqs. phase, of an emulsifier consisting of a mixt. of a 10 - 25C alkali metal alkylsulphonate and/or alkylsulphate, and a satd. or unsatd. fatty acid polyoxyethylate with 10 - 25C atoms in the carboxylic acid group, and 3 - 15 alkylene oxide units. The unsatd. comonomer is sodium vinylsulphonate. The emulsifier consists of a mixt. of a 13 - 17C alkali metal alkylsulphonate and an oleic acid oxyethylate with S ethylene oxide units.

    Abstract: Continuous distillation process by means of a rectification column for producing stabilised unsaturated carboxylic acids, for example hydroquinone-stabilised acrylic acid, in which a) crude acrylic acid, consisting of acrylic acid and high-boiling by-products, is fed to the rectification column, b) acrylic acid is drawn off as the top product, c) a mixture of high-boiling by-products/acrylic acid is drawn off as the bottom product, d) a stabiliser, for example hydroquinone, is added to the distillate and to the reflux, and e) a temperature-resistant, highly active inhibitor is added to the rectification column a few plates below the reflux supply.
