Abstract
This invention relates to compositions and a process for stabilizing or solubilize a phenolic resin containing a mixture of linear phenolic resins and calixarenes. The process comprises contacting the phenolic resin with an epoxide, to at least partially alkoxylate the phenolic hydroxyl groups of the calixarenes. This process forms a stabilized or solubilized phenolic resin with an increased solubility in a hydrocarbon solvent.
