Reaction Steps
745.4 Parts of rosin addition product (b) are esterified with 196 parts of maleic anhydride, while stirring at 50° to 85° C.; after diluting the mixture with water, 264.6 to 277.2 parts of sodium sulfite (as an aqueous solution) are introduced by stirring within 15 to 120 minutes at 40° to 80° C., and stirring is continued for 1 hour, after the mixture has become clearly water-soluble. The amount of water added may be in the range of from 50 to 85% by weight of the final solution. By way of spray-drying, a light yellow powder is obtained which exhibits a low electrolyte content.
