    Abstract: Examples describe the preparation of coloured polymers by the radical copolymerization of (1) lorol acrylate, N-vinylimidazole and an azo dye of formula (2) styrene, 2-ethylhexyl acrylate, the above dye, and optionally N-vinylbenzimidazole; (3) as (1) and (2) in which the dye is replaced by the dyes (4) lorol acrylate and a dye of formula which may be replaced by the dyes ALSO:A mineral oil contains as stabilizer, colorant and V.I improver an oil-soluble copolymer of (by weight) (a) 0 to 99% of at least one aromatic polymerizable compound; (b) 0 to 99% of at least one ester of a polymerizable carboxylic acid, the total of (a) and (b) being at least 20%; (c) 0 to 20% of at least one nitrogenous polymerizable compound; (d) 1 to 20% of at least one dye bearing a polymerizable group; and (e) 0 to 40% of at least one further co-monomer. Component (d) may be replaced by (f) a co-monomer having a reactive group to which, after polymerization, is attached (g) a dye having a complementary reactive group. Component (a) may be styrene or a substituted styrene; (b) may be an acrylate, methacrylate, ethacrylate, chloroacrylate, phenylacrylate or an ester of cronotic, fumaric, maleic, itaconic, mesaconic, or citraconic acid; (c) may be a vinyl-substituted organic base (many specified), another vinyl-substituted nitrogen compound, or an N-alkyl acrylic or methacrylic amide; the dyestuff (d) may contain a vinyl or acrylic grouping (many examples of azo and anthraquinone dyes given: triphenylmethane dyes may also be used); component (e) may be butadiene, a vinyl or vinylidene compound, an acrylate or methacrylate or acrylonitrile. Where (d) is replaced by (f) plus (g), there may be, for example an amide group in (f) and an N-methylolamide group in (g), or a hydroxy group in (f) and an isocyanate group in (g); other examples are suggested. The oil may contain from 0.025% to 2% of the polymer.

    Abstract: Glass fibres are dyed or printed with pigments using as a binder a film-forming polymer which becomes cross-linked under the influence of a proton-acceptor and using an amino-silane or a hydrocarbon wax as an agent having hydrophobic action to promote adhesion between the binder and the glass surface, the process being carried out in the presence of a proton-acceptor, and the treated fibres being finally dried and heated. The polymers are those having groups, for example amino or hydroxy groups, which by means of proton acceptors can enter into covalent bonds with themselves or other groups. The preferred polymers are copolymers bearing hydrocarbon radicals as side chains in which a halogen atom and a hydroxyl group are attached to two adjacent carbon atoms, particularly a polymer obtained by co-polymerising 2-hydroxy-3-chloropropyl acrylate with other monomers. The proton-acceptor may be an alkali metal hydroxide, carbonate or bicarbonate, amonia or an organic amine; it may be provided as the alkali present in the glass. The glass fibres may be treated as such, mixed with other fibres or in the form of fabric. In the treatment, the various components can be applied separately or in combination. Examples illustrate the use of copper phthalocyanine, azo dyes and carbon black as the pigments.

    Abstract: Print pastes for textiles and other substrates comprise an oil-in-water emulsion containing a pigment or vat dye and, as a binder, a water-soluble copolymer of:-(1) to 70 parts by weight of a neutral ester of an a , b -ethylenically unsaturated mono-or di-carboxylic acid and an aliphatic or cycloaliphatic alcohol having at least 6 carbon atoms; (2) 1 to 40 parts by weight of an ethylenically unsaturated polymerizable nitrogenous compound containing at least one N-methylol ether group; (3) 4 to 15 parts by weight of a polymerizable a , b -ethylenically unsaturated mono- or di-carboxylic acid; (4) 0 to 20 parts by weight of an ethylenically unsaturated polymerizable hydroxy compound; and (5) 0 to 70 parts by weight of another ethylenically unsaturated monomer; the total amount or major proportion of the free carboxylic groups in the copolymer having been neutralized by ammonia or a nitrogenous organic base (e.g. methylamine, triethylamine, dimethy-ethanol-amine, triethanolamine, piperidine or morpholine). Suitble monomer components of the copolymer include (1) esters of acrylic, methacrylic, crotonic, maleic or fumaric acid with hexanol, heptanol, octanol, isooctanol, dodecanol, a -ethylhexanol, cyclohexanol or hexanediol; (2) N-methylol ethers of unsaturated amides and imides and unsaturated compounds containing a ureido, aminotriazine, dicyanodiamide, carbamic acid, thiocarbamic acid; glyoxal-monoureine or glyoxal diureine group; (3) crotonic, citraconic, itaconic, mesaconic, maleic, fumaric and, preferably, acrylic or methacrylic acid; (4) monoesters of polyhydric alcohols and ethylenically unsaturated carboxylic acids, monovinyl ethers of polyhydric alcohols, allyl alcohol and hydroxy-containing bicycloheptene derivatives; (5) styrene, esters of acrylic or methacrylic acid with alcohols having up to 5 carbon atoms, vinyl esters (including versatic esters), butadiene, isoprene, acrylonitrile, methacrylonitrile, acrylamide and methacrylamide and their N-alkyl derivatives, vinyl chloride, vinylidene chloride, vinyl ethyl ether, vinyl ethyl ketone, N-vinylimidazole, N-vinyl pyrrolidone and N-vinyl caprolactam.

    Abstract: Laurolactam is partially polymerized at 200-340 DEG C. and autogenous pressure in the presence of 10-300 mole per cent of water, the water is removed and the polymerization continued at 270-340 DEG C. Before polymerization the reactants may be freed of oxygen. 0.05-2 mole per cent of a chain terminator, e.g. acetic, propionic, butyric, benzoic or stearic acid or dodecylamine, may be added before or during polymerization. Other additives may be fillers, fibres, pigments and dyes. Both polymerization stages may be conducted under an inert atmosphere. The pressure of the first may be up to 73 atmospheres; that of the second atmospherics sub- or super-atmospheric. The water may be removed by releasing the pressure and heating. The products may be extruded as fibres directly from the bottom of the pressure vessel. They may be injection moulded, extruded, or fluidized bed coated to produce rods, gears, pipe, film, sheeting bristles or fibres.
