Abstract
There are provided rubber compositions comprising an elastomer comprising a rubber chosen from acrylonitrile-butadiene, hydrogenated acrylonitrile-butadiene, carboxylated acrylonitrile-butadiene and mixtures thereof; reinforcing fibers chosen from aramid fibers, carbon fibers, polyester fibers, glass fibers, nylon fibers and mixtures thereof, and/or nanometric filamentary structures chosen from nanowires, nanorods, nanofibers, nanoribbons, nanotubes and mixtures thereof, the nanometric filamentary structures being functionalized or unfunctionalized; and a filler chosen from carbon black and silica. These compositions can be cured or uncured and they can be used for preparing various articles. Methods for preparing such compositions are also disclosed.
