Four reactive liquid rubbers with different end‐groups but the same main chain (carboxyl‐, epoxy‐, amino‐terminated and non‐functional butadiene–acrylonitrile random copolymers) were employed in the same epoxy system, the diglycidyl ether of bisphenol A and 4,4′‐diamino‐3,3′‐dimethyldicyclohexyl methane cured at 50°C. The effects of the end‐groups of the liquid rubber on the morphology, phase compositions, sub‐structure inside the particles, interface between the phases and the mechanical properties were determined. The effects were related to the reactivity and the miscibility of the additive.
