Reaction Steps
After having added 2.5 parts of sodium hydroxide, 489 parts of the rosin-naphthol-glycerol ester described under (a) are reacted according to Example 17(b) with 772 parts of ethylene oxide. The viscous rosin-glycerol addition product obtained is reddish brown and contains 18 mols of ethylene oxide. The cloud point in a 25% butyl diglycol solution is found at 59° C.
