Abstract
Disclosed herein are highly stable styrenated phenolic compositions that are liquids at room temperature, and polymer articles and lubricant compositions containing such styrenated phenolic compositions. Also disclosed are processes for forming such styrenated phenolic compositions, which processes afford distyrenated phenolics assaying at 70% minimum by total GC area, comprising reacting styrene with one or more phenolics, e.g., at least one of phenol, p-cresol and/or o-cresol, in the presence of an acid catalyst, preferably a sulfonic acid catalyst, at elevated temperature, wherein the resulting product mixture comprises one or more monostyrenated phenolics, one or more distyrenated phenolics, and one or more tristyrenated phenolics.
