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.
本文披露了高度稳定的苯乙烯化酚类组合物,它们在室温下是液体,并且包含这种苯乙烯化酚类组合物的聚合物制品和润滑剂组合物。还披露了形成这种苯乙烯化酚类组合物的过程,该过程得到至少占总GC面积的70%的二苯乙烯化酚,包括在存在酸催化剂,优选为磺酸催化剂下,在升高的温度下,将苯乙烯与一个或多个酚反应,例如至少一个酚酚,对甲苯酚和/或邻甲酚,其中所得到的产物混合物包括一个或多个单苯乙烯化酚类,一个或多个二苯乙烯化酚类和一个或多个三苯乙烯化酚类。
