    摘要: Condensates of arenesulfonic acids and formaldehyde are prepared by sulfonating arenes obtainable by thermal cracking of a naphthenic residue oil and fractional distillation of the cracked products of the fraction obtained at 100-120.degree. C. under atmospheric pressure, sulfonating this aromatics fraction with oleum at 120.degree.-160.degree. C. using an amount of from 0.7 to 1.2 parts by weight of oleum having an SO.sub.3 content of 24% by weight per part by weight of aromatics fraction, and subsequently condensing the arenesulfonic acids with formaldehyde in a conventional manner, and are used as dispersants, in particular for preparing dye formulations.

    摘要: Aqueous polyester dispersions are prepared by(a) condensing an aromatic dicarboxylic acid or ester with at least one diol to give a prepolymer having an acid number of from 2 to 8,(b) reacting the prepolymer with at least one molecular weight enhancer compound, e.g. trimellitic anhydride to give a polyester having an acid number of from 40 to 60, and(c) dispersing the polyester in an aqueous medium to form an aqueous dispersion by adding an aqueous mixture of ammonia and an amine in a molar ratio of from 10:1 to 1:10 to a melt of the polyester which has a temperature within the range from 150.degree. to 230.degree. C.,and are used as sizes for sizing filament warp yarns.
