More Information
Summary:The invention relates to surface-active azo compounds obtainable by reacting azo compounds corresponding to the following general formula (I): (I) in which X and Y are the same or different and represent +TR and R represents C1-C4-alkyl, with at least one C10-C18-paraffin disulphonic acid dihalide in aqueous medium or a solvent or solvent mixture which is inert to the reactants under the process conditions and in which the reactants are at least partly soluble, at temperatures in the range of from 0 DEG to + DEG C. and in the presence of a base in a quantity substantially equivalent to the hydrolysable halogen, the reaction being accompanied by the elimination of hydrogen halide. The new azo compounds give low electrolyte, low-foam dispersions in emulsion and dispersion polymersation.
