Abstract
A method for preparing a nanoclay-filled thermoplastic vulcanizate, the method comprising introducing an olefinic thermoplastic vulcanizate, a functionalized thermoplastic resin, and a surface-modified nanoclay, where the blending takes place at a temperature above the melt temperature of the thermoplastic vulcanizate but below the temperature at which the surface-modified nanoclay degrades.
