Summary: | The present invention relates to a pneumatic tire having an air barrier layer, particularly an integral pneumatic tire innerliner, for prevention, or retardation, of air permeation from its inner chamber to the atmosphere through the carcass of the tire. The innerliner is comprised of an annular, cylindrical, hoop of a film having its ends overlapped and heat sealed together. The film is comprised of a continuous thermoplastic polymer phase which contains a dispersion therein of cured rubber domains, particularly cured low unsaturation rubber domains. In one embodiment, one surface of the film contains a thin bonding layer to aid in bonding the film to an unsaturated rubber-containing tire carcass. In one embodiment, the overlapping portion of the ends of the film have a thin rubber layer positioned therebetween. |
