Certain phosphorus-containing compounds are described herein which are novel latent catalysts for promoting the reaction between vicinal epoxides and phenols and/or carboxylic acids (or anhydrides). Precatalyzed epoxy resins are easily prepared using such catalysts.
本文描述了一些新型潜在催化剂,其中包含
磷元素的化合物,用于促进邻二氧化环氧和
酚和/或
羧酸(或酐)之间的反应。使用这种催化剂可以轻松制备预催化环氧
树脂。
