ABSTRACT:
The present invention relates to a pneumatic rubber tire having an integral innerliner characterized by a top layer and a rubber laminate having at least three additional layers. At least two of the three layers are barrier layers and comprise a sulfur cured rubber composition containing, based on 100 parts by weight of rubber, 100 parts of an acrylonitrile/diene copolymer rubber having an acrylonitrile content ranging from about 30 to about 45 percent and from about 25 to about 150 parts by weight of a platy filler selected from the group consisting of talc, clay, mica or mixtures thereof. The thickness of each acrylonitrile/diene barrier layer ranges from about 25 microns to 380 microns. Between the two layers of acrylonitrile/diene copolymer is at least one non-barrier layer of a sulfur cured rubber selected from the group consisting of natural rubber, halogenated butyl rubber, butyl rubber, cis-1,4-polyisoprene, styrene-butadiene rubber, cis-1,4-polybutadiene, styrene/isoprene/butadiene rubber or mixtures thereof. The laminate may contain from about 3 to 100 individual layers.
