Versuchsvorschrift

652 Parts of the above rosin alcohol oxalkylation product are esterified with 98 parts of maleic anhydride at 50° to 80° C., while stirring, and after diluting the mixture with water, from 132.3 to 138.6 parts of sodium sulfite (as an aqueous solution) are introduced by stirring at 40° to 80° C. within 15 to 120 minutes, until the mixture has become clearly water-soluble. Subsequently, stirring is continued for 1 hour. The amount of water added may be in the range of from 50 to 85% by weight of the final solution.
