Reaction Steps
After having added 0.4 part of zinc chloride, 302 parts of colophony are slowly heated to 100° C. together with 128 parts of 4-chlorophenol, while passing nitrogen through the mixture, and said temperature is maintained for 2 hours. Subsequently the temperature is increased to 200° to 210° C., until after about 1 hour the reaction product is free from halogen. After cooling there is obtained a clear rosin having a softening point of about 105° C.
