摘要：
The process of reacting an epoxy resin with a reactive hydrogen-containing compound or a carboxylic acid anhydride in the presence of a phosphonium catalyst is improved by employing a phosphonium compound having an amino substituent on the cation portion of the phosphonium compound as the catalyst. The invention also concerns precatalyzed epoxy resin compositions, curable compositions and cured compositions.
