Abstract
A layered structure suitable for use in a pneumatic tire as an innerliner is prepared by directly bonding a fluid permeation prevention film and an adhesive tie layer. Prior to the bonding, the fluid permeation prevention layer is treated to remove any residual plasticizers or oils on the surface of the film. The tie layer comprises 100 weight % of at least one halogenated isobutylene containing elastomer and about 1 to about 20 parts per hundred (phr) of at least one tackifier. The fluid permeation prevention film comprises an elastomeric component dispersed in a vulcanized or partially vulcanized state, as a discontinuous phase, in a matrix of the thermoplastic resin component. The two layers of the layered structure may be separately extruded and then adhered to each other or adhered to each other during a calendaring operation wherein the adhesive tie layer composition is coated onto the treated film.
