Toughness enhancement of nylon 6 with epoxidized
natural rubber has been successfully achieved. The impact
strength of the blends increased with ENR content whereas
their tensile properties decreased with increasing ENR.
Rubber content was the key factor for toughness enhancement.
Morphology of ENR was changed from small particles
to large patches of rubber after vulcanization. As
a result, the compounded rubber provided superior tensile
properties but inferior impact strength of the blends in
comparison to the uncompounded rubber.
