摘要： The performance of expoxy resins in several end-uses is enhanced by the presence of small quantities of hydrolyzed resin terminated by alpha -glycol groups. The invention is a process in which a mixture that contains liquid epoxy resin and water is reacted at elevated temperatures in order to hydrolyze epoxy groups into alpha -glycol groups, characterized in that: (1) the reaction temperature is between 130 DEG C and 200 DEG C; (2) the reaction mixture contains between 0.5 and 10 parts water per 100 parts resin by weight; and (3) the mixture contains 0 to 1 weight percent organic solvents and 0 to 100 ppm each of: organic acids, organic diacids, phosphonium compounds, and alkali or alkaline earth metals and their salts. The process raises the level of alpha -glycol groups in the resin, but uses no solvents or catalysts, so that it is easy to clean up the resulting resin.
