Abstract
A hydrocarbon insoluble polar fraction is extracted from guayule-like resins by adding a hydrocarbon solvent containing a small amount of water therein to the guayule-like resins and mixing the same. A two-phased solution is formed with the hydrocarbon insoluble polar fraction being located in the water phase. The addition of water to the hydrocarbon increases the yield of the insoluble polar fraction as well as the acid number and the amount of ketoalcohol located therein.
