Reaction Steps
After having added 2.1 parts of sodium hydroxide, 393.5 parts of the rosin-phenol compound described under (a) are oxethylated at 140° to 150° C. in accordance with Example 17(b). The resulting slightly viscous rosin-phenol addition product is olive green and contains 12 mols of ethylene oxide. The cloud point in butyl diglycol is found at 50.5° C.
