Abstract

The present invention provides polymeric nanoparticles comprising triblock and optionally diblock copolymer chains. The architecture of the polymeric nanoparticles may be controlled, resulting in nanoparticles having non-spherical shapes. The present invention also provides a method of preparing the polymeric nanoparticles and a rubber article such as a tire manufactured from a formulation comprising the polymer nanoparticles.
