The mechanical and thermal behavior of composites consisting ona styrene?butadiene rubber(SBR) matrix with a sulphur/accelerators system and multiwalled carbon nanotubes functionalized with poly- 4-vinylpyridine (MWCNT-PVP) as reinforcement, were studied. The materials were tested with stress- strain tensile tests, DMTA and DSC for thermal properties. A strong increase in the plastic behavior with slight decrease of its elastic Modulus and Tg led to unexpected results
