Abstract
This invention relates to an alkoxylated calixarene resin comprising one or more modified calixarene alkoxylate compounds. The invention also relates to a process for preparing a solubilized alkoxylated calixarene resin comprising reacting a phenolic resin mixture, comprising linear phenolic resins and calixarene compounds having phenolic hydroxyl groups, with one or more epoxide-containing compounds to alkoxylate one or more of the phenolic hydroxyl groups of the calixarene compounds to form a solubilized phenolic resin mixture, and reacting the solubilized phenolic resin mixture with one or more alkylene oxides.
