Abstract

Compositions and methods are included for preparing a hairy polymeric nanoparticle including first and second shell block polymer arms are at least partially phase-separated and surround a polymeric core. One type of polymeric arm can have a greater polarity than the other type(s) of polymeric arms. A rubber composition including the hairy nanoparticles is also provided.
