A polymer nanocomposite composition having sufficiently low air permeability to be usefull as a tire inner liner, among other things, is prepared by blending a layered material with a metal processible non-ionic first polymer having a number average molecular weight greater than 50,000 g/mole and a second non-ionic polymer compatible with the first polymer and having a number average molecular weight less than that of the first polymer. |
