Abstract: The present application is directed to novel discrete carbon nanotubes with a surface modification that disperses well in elastomers and crosslinks elastomers to the surface of the discrete carbon nanotubes, or in the vicinity of the discrete carbon nanotube surface. Significant improvements in the performance of elastomeric formulations with a plurality of discrete carbon nanotubes with a surface modification and silica and/or carbon black result, for example, improved abrasion resistance while at the same time providing a reduced hysteresis effect on cyclic deformation. These improved properties are highly desired for fuel efficient and longer wear life tire formulations.
