Disclosed herein are graft polymers having a copolymer backbone and polycyclic aromatic hydrocarbon branches for use as a nanofiller dispersant and methods for making the same. Also disclosed are elastomeric nanocomposite compositions comprising a halobutyl rubber matrix, nanoparticles of graphite or grapheme, and the graft polymer. Such elastomeric nanocomposite compositions are suitable as tire innerliners or innertubes.

    L'invention concerne des polymères greffés ayant un squelette de copolymère et des ramifications d'hydrocarbure aromatique polycyclique qu'on utilise en tant que dispersant de nanocharge et leurs procédés de fabrication. L'invention concerne également des compositions de nanocomposites élastomères comprenant une matrice de caoutchouc halobutyle, des nanoparticules de graphite ou de graphène et le polymère greffé. De telles compositions de nanocomposites élastomères sont utiles comme revêtements intérieurs ou chambres à air de pneumatiques.
