    Abstract: A process for the production of copolymers comprises polymerizing at a temperature of 50 DEG to 150 DEG C. 1 to 50% by weight of a monomer of the general formula in which R and R1 are hydrogen or methyl and R11 is an alkyl radical containing 1 to 4 carbon atoms or an alkyl ether radical of formula -(CH2)2-O-(CH2)n-CH3 where n is 1 to 3, with 99 to 50% by weight of another ethylenically unsaturated polymerizable compound. The ether ester may be 1-acryloxy-1-ethoxyethane, 1-methacryloxy-1-ethoxyethane, 1-methacryloxy-1-butoxyethane, 1-acryloxy-1-isobutoxyethane, 1-methacryloxy-1-isobutoxyethane, 1-methacryloxy-1-[b -methoxyethoxy]-ethane, 1-acryloxy-1-[b -ethoxy-ethoxy]-ethane, 1-methacryloxy-1-methoxyethane, 1-crotonyloxy-1-ethoxyethane and 1-crotonyloxy-1-methoxy ethane. Many suitable comonomers are listed including the unsaturated carboxylic acids and their esters, amides, nitriles and anhydrides, unsaturated aldehydes and ketones, unsaturated alcohols and their esters and ethers, olefins and diolefins, vinyl aromatic hydrocarbons and halogenated derivatives thereof, vinyl and vinylidene chloride and vinyl heterocyclic compounds. Polymerization may be effected in the presence of solvents and diluents, e.g. alcohols, ketones, ethers, amides, aromatics and heterocyclics; catalysts, e.g. organic peroxides and hydroperoxides and azo compounds; and chain transfer agents, e.g. mercaptans. Examples describe the polymerization of 1-acryloxy-1-ethoxyethane with (1) butyl acrylate and styrene; (2) butyl acrylate and acrylamide; (3) vinyl propionate and (11) butyl acrylate; of (4) 1-methacryloxy-1-isobutoxyethane with vinyl propionate and methyl methacrylate; of (5) 1-methacryloxy-1-[b -methoxyethoxy]-ethane with methyl methacrylate and butyl acrylate; of (6) 1-crotonyloxy-1-methoxyethane with acrylic acid, ethyl acrylate and styrene; of (7) 1-methacryloxy-1-butoxyethane with t.-butyl acrylate and acrylonitrile; of (8) 1-acryloxy-1-[b -ethoxyethoxy]-ethane with N-butyl acrylamide, butyl acrylate and dimethyl itaconate; of (9) 1-methacryloxy-1-ethoxy ethane with N-butoxymethyl methacrylamide, dichlorostyrene and dibutyl fumarate; and of (10) 1-crotonyl-1-ethoxy ethane with butanediol monoacrylate, dibutyl maleate and styrene. The copolymers may be dissolved in organic solvents, e.g. dioxane, toluene, cyclohexanone, butanol and butyl acetate, optionally together with urea-formaldehyde condensates, butanol etherified urea-formaldehyde condensates, melamineformaldehyde condensates, phenol-formaldehyde condensates, polyamides, aliphatic or aromatic epoxy resins, non-cross-linked reaction products of a dicarboxylic acid and pyrrole, and optionally curing catalysts such as phosphoric acid, and used for the production of films, lacquers, varnishes, coatings for wood and metals, for impregnating, textile finishes and pigment printing pastes, and cross-linked by heating.

    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.
