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.
