Versuchsvorschrift

98 Parts of maleic anhydride are added, while stirring, to 742 parts of the above rosin acid oxalkylation product at 50° to 80° C.; after diluting the mixture with water, 132.3 to 138.6 parts of sodium sulfite (as an aqueous solution) are stirred in at 40° to 80° C. within 15 to 120 minutes, until the mixture has formed a clear solution. 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.
