    Abstract: Process for printing synthetic fibres composed of polyester, triacetate, acetate and polyamide, and blends thereof, with disperse dyes by the discharge or discharge-resist process using a discharging agent comprising a mixture of a) 5 to 100 parts by weight of at least one compound of the formula and/ôor of an alkali metal or ammonium thiocyanate, b) 5 to 95 parts by weight of an alkali metal or ammonium hydroxymethanesulphinate, alkali metal or ammonium hydroxyethanesulphinate or an ammonia derivative containing at least one radical of an alkali metal or ammonium salt of methane- or ethane-sulphinic acid, and c) 5 to 90 parts by weight of a reducing carbohydrate derivative.

    Abstract: Crosslinked copolymers containing crosslinkable groups based on acrylic acid or methacrylic acid which are obtainable by copolymerisation of (a) from 50 to 99 parts by weight of acrylic acid and/or methacrylic acid, (b) from 1 to 50 parts by weight of at least one N-methylol(meth)acrylamide, or derivatives thereof, (c) from 50 to 10000 ppm, based on monomers (a) and (b), of an at least bifunctional crosslinking agent and (d) from 0 to 49 parts by weight of other monoethylenically unsaturated monomers, in the presence of polymerisation initiators which form free radicals, a process for the preparation of the crosslinkable copolymers by copolymerising the monomers (a), (b), (c) and, if used, (d) in the aqueous phase of a water-in-oil emulsion, and the use of the copolymers as thickeners for textile printing pastes.

    Abstract: Process for the preparation of finely divided polymer powders by polymerisation of water-soluble monomers in the aqueous phase of a water-in-oil emulsion in the presence of water-in-oil emulsifiers and polymerisation initiators, removal of water from the resulting water-in-oil polymer suspension by an azeotropic method and isolation of the suspended finely divided polymer powder, wherein either the polymerisation of the water-soluble monomers is carried out in the presence of 0.1 to 10% by weight, based on the monomers used in the polymerisation, of protective colloids or the protective colloids are added to the water-in-oil polymer suspension after the end of the polymerisation. The polymerisation is preferably carried out in the presence of a wetting agent. The finely divided pulverulent polymers are used as flocculants or thickeners for aqueous systems.
