Products of condensation of phenol / formaldehyde, water-soluble sulfomethylated and their application as dispersing agents

摘要

Water-soluble condensation products which are obtained by reacting mononuclear phenol/formaldehyde/bisulphite condensation products with formaldehyde and, if appropriate, notrogen-containing compounds of a type which can react with at least 2 equivalents of formaldehyde, can be used as dispersing agents.
