Abstract
Liquid modified epoxy resins are prepared by reacting a drying oil with a diepoxide in the presence of certain alkali or alkaline earth metal compounds, preferably a lithium soap such as lithium ricinoleate. The drying oil may be modified by reacting it with maleic acid, maleic anhydride, or fumaric acid to increase the drying rate.
