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