Epoxy and epoxy novolak resins are impact modified by adding an effective amount of a acrylamide diene nitrile rubber terpolymer to the resin. In a preferred embodiment, the acrylamide diene nitrile rubber includes an acid or ester group attached to the acrylamide portion of the polymer generally through a thiol group. The liquid terpolymer is reacted in the presence of acid catalysts with the resin to provide impact modification.
