Abstract

Solid or semi-solid epoxy resins having the following general formula < IMAGE > where n is from 1.2 to 6.5 are prepared by the exothermic reaction between bisphenol A and epichlorhydrin, in the presence of a slight excess of alkali and with the exclusion of oxygen from the reaction medium.
