Zusammenfassung:Epoxy resins containing aliphatic, non-hydrolyzable chlorine atoms are prepared by hydrochlorinating an epoxy resin thereby forming a chlorohydrin intermediate product; reacting this intermediate product with epichlorohydrin in the presence of a Lewis acid; and dehydrochlorinating the resultant product. The epoxy resins containing aliphatic, non-hydrolyzable chlorine atoms are useful for some coating formulations.
