    摘要： New sulphur-containing polyethers based on optionally polymeric thioalkylene oxides and polyalkylene oxides, method for their preparation and their use as breakers for water-in-oil emulsions, in particular, as breakers for crude oil emulsions. The polyethers are of the formula ##STR1## in which R.sub.1 and R.sub.2, independently of each other, represent hydrogen and/or a straight-chain or branched C.sub.1 to C.sub.20 alkyl group,R.sub.3 and R.sub.4, independently of each other and independently of adjacent ##STR2## groups, represent in each case hydrogen, a straight-chain or branched C.sub.1 to C.sub.20 alkyl group and/or for --A--O--B, whereA denotes a straight-chain or branched C.sub.1 to C.sub.20 alkylene group andB denotes a straight-chain or branched C.sub.1 to C.sub.20 alkylene-OH group or a ##STR3## group with R.sub.1 and R.sub.2 as defined above, n represents an integer from 1 to 100 andm represents an integer from 10 to 2,500.

    摘要： Solid dyestuff formulations having excellent dyebath stability are obtained in an economical manner by mixing a water-insoluble textile dyestuff with a dispersant and a carboxyl-containing copolymer of(a) an .alpha.,.beta.-ethylenically unsaturated monocarboxylic acid,(b) a non-basic ester of an .alpha.,.beta.-ethylenically unsaturated monocarboxylic acid, and(c) an unsaturated aliphatic or aromatic hydrocarbon or acrylonitrile,bead-milling the mixture down to a particle size of, preferably, 1-2.mu., and then spray-drying the ground mixture. If desired the dispersant can also be added during the synthesis of the dyestuff, as a consequence of which early addition the milling process can be dispensed with.
