    Abstract: An N-(b -trichloro-a -alkoxyethyl) amide of an a , b -unsaturated carboxylic acid is polymerized by bulk, solution, emulsion or suspension polymerization with at least one other ethylenically unsaturated polymerizable compound. The 'amide' compound has the general formula: where R is a hydrogen or halogen atom, an alkyl or a substituted alkyl radical and R1 is an alkyl, aralkyl or alkenyl radical which may be linear or branched and which may also contain hetero atoms of further substituents Lists of suitable radicals for R1 are given. Ethylenically unsaturated polymerizable compounds mentioned are a -b -unsaturated carboxylic and dicarboxylic acids and their esters, amides, substituted amides and nitriles, such as acrylic methacrylic and maleic acids; methyl ethyl and butyl-acrylates; acrylonitrile and methacrylonitrile; acrylamide and methacrylamide; vinyl esters such as vinyl acetate and propionate; unsaturated polymerizable aldehydes, ketones and alcohols and their esters and ethers such as acrolein, methyl vinyl ketone, allyl and methallyl alcohols, allylmethylether and allyl acetate; and polymerizable hydrocarbons containing a single unsaturation and diene hydrocarbons such as ethylene, propylene, butadiene or isoprene; vinyl ethers such as vinyl methyl or ethyl ether; vinyl or vinylidene halides such as vinyl chloride and vinylidene chloride; and aromatic and heterocyclic N- or C-vinyl compounds such as styrene, alkyl-styrenes, dichlorostyrene, N-vinylpyrrolidone and N-vinylcarbazole. The polymers may be cross-linked by heating to temperatures of 160 to 190 DEG C., an acid being present if desired. They may also be cross-linked with compounds with react with the alkoxyethyl groups of the polymers e.g. condensation products of urea, melamine, phenol, or resorcinol with formaldehyde, and their reaction products with alcohols. Epoxy resins alkyd resins and poly-alcohols may also be used. In Example 1, N-(b -trichloro-a -methoxyethyl) methacrylamide is copolymerized with butyl acrylate using a butanol solution and dilauryl peroxide and dodecylmercaptan, while in Example 2 N-b -trichloro-a -methoxyethyl) methacrylamide is copolymerized with styrene and butyl acrylate in an emulsion there being present an alkali salt of a sulphonated oxyethylation product of a fatty alcohol mixture (C16-C18), potassium persulphate and sodium pyrophosphate in water.

    Abstract: 4,6-Dimethyl -7- acryloyl - hydroxyethyl - amino-coumarin of the formula: is produced from 4,6-dimethyl -7- b-hydroxyethylamino-coumarin by esterification with acrylic acid. ALSO: Fluorescent copolymers are obtained by emulsion, solution, bulk, suspension or precipitation polymerization of fluorescent dyes containing a polymerizable olefinic group outside of the fluorescent system with non-coloured, non-fluorescent compounds containing a polymerizable olefinic group and groups which are accessible to condensation or addition reactions and, optionally, with other polymerizable non-coloured, non-fluorescent compounds. Suitable fluorescent dyes are of the stilbene, triarylmethane coumarin, aminonaphthalimide, aminoterephthalic diamide and azomonomethinecyanine series; their polymerizable groups, e.g. acryloyl or allyl, may be introduced by way of acid, hydroxy or amino groups. In the examples (1) an emulsion polymer of butyl acrylate, N-methylolmethacrylamide, methacrylamide and 4, 6 - dimethyl - 7 - acryloyl - hydroxyethylaminocoumarin is prepared by emulsion polymerization and (2) a copolymer of butyl acrylate, N-methylolmethacrylamide and 4, 6-dimethyl-7-acryloylhydroxyethylamino-coumarin is prepared in ethanol solution. ALSO: Textiles, e.g. of cotton or polypropylene, are simultaneously dyed in fluorescent shades and/or optically brightened and finished by applying thereto a solution or dispersion of a cross-linkable copolymer obtained by copolymerization of fluorescent dyes containing a polymerizable olefinic group outside of the fluorescent system with non-coloured, non-fluorescent compounds containing polymerizable olefinic groups which are accessible to condensation or addition reactions and optionally with other polymerizable non-coloured, non-fluorescent compounds and cross-linking the copolymer either directly or with the aid of suitable bi-or poly-functional compounds. Specified fluorescent dyes are from the stilbene, triarylmethane, coumarin, aminonaphthalimide, aminoterephthalic diamide and azomonomethinecyanine series. The polymerizable olefinic groups, e.g. acryloyl or allyl, may be attached by way of acid, hydroxy or amino groups. The copolymer may be obtained by the methods of emulsion, solution, bulk, suspension or precipitation polymerization. Examples are given.

    Abstract: Polymeric substances are coloured by graft polymerizing thereon a dye bearing a polymerizable olefinic group and, if desired, other monomers which are colourless. Polymers specified are polymers and copolymers of olefinic monomers, polyaldehydes, polymers of lactams, lactones, cyclic ethers sulphides and amines, phenol, urea, melamine and alkyd resins, polyesters, polyamides, polycarbonates, polyurethanes, epoxy resins, cellulose, proteins and rubber. The polymerizable dyes may be of the azo, anthraquinone, triarylmethane, azomethane or phthalocyanine type. Grafting may be effected by means of a free-radical initiator or high-energy irradiation. The substrate monomer may be dissolved in the grafting monomer, or may be used in the form of a solution in an organic solvent or as an aqueous emulsion, or may be in the form of a film or fibre. The examples describe: (1) grafting by means of X-rays isobutyl 1 - amino - 4 - acryloylaminoanthraquinone - 2 - carboxylate and butyl acrylate on to an aqueous dispersion of a copolymer of butyl acrylate and methylol methacrylamide, followed by cross-linking the product with the dimethylol compound of butanediol-1, 4-diurethane; (2) as in (1), but using as the grafting monomer the coupling product of diazotized 2-amino-4-sulphonic acid-41-acryloylaminodiphenyl sulphone and 3-sulphonic acid-7-aminonaphthol-1; (3) grafting by means of X-rays the coupling product of diazotized 1-acryloylamino-4-aminobenzene and 1-phenyl-(21-chloro-41-sulphonic acid)-3-methylpyrazolone-5 on to an aqueous dispersion of a copolymer of butyl acrylate acrylonitrile and methylol methacrylamide, and cross-linking the product with the dimethylol compound of butanediol-1, 4-diurethane; (4) as in (3), but grafting by means of potassium persulphate; and (5) as in (3), but using a copolymer of butyl acrylate and methacrylamide as the grafting substrate. The resulting products are used for colouring cotton fabrics. Specifications 877,402, 914,354, 946,472, 948,694, and 952,810 are referred to.ALSO:Fibrous materials or films of polymeric organic substances are coloured by graft-polymerizing a dye containing olefinic unsaturated groups with the substance of the fibres or films. Alternatively the materials, e.g. fabrics, are dyed by applying thereto an aqueous dispersion of a polymeric substance on which has been grafted a dye bearing a polymerizable olefinic group. The examples describe the application to cotton fabrics of aqueous dispersions of graft copolymers containing the dimethylol compound of butanediol-1, 4-diurethane as a cross-linking agent, followed by drying at 140 DEG C., the graft copolymers specified being obtained by graftin: (1) isobutyl 1-amino-4-acryloylaminoanthraquinone 2-carboxylate and butyl acrylate on to a copolymer of butyl acrylate and methylol methacrylamide; (2) the coupling product of diazotized 2-amino-4-sulphonic acid-41-acryloylamino-diphenyl sulphone and 3-sulphonic acid-7-aminonaphthol-1 on to a copolymer as in (1); (3) the coupling product of diazotized 1-acryloylamino-4-aminobenzene and 1-phenyl-(21-chloro-41-sulphonic acid)-3-methylpyrazolone-5 on to a copolymer of butyl acrylate, acrylonitrile and methylol methacrylamide; and (5) a dye as in (3) on to a copolymer of butyl acrylate and methacrylamide. The dyeing of textiles such as polypropylene textiles by direct graft-polymerization with polymerizable dyes is referred to.
