ABSTRACT:
The invention relates to novel air barriers made from elastomeric compositions. In particular, the invention relates to novel air barriers such as innerliners, air sleeves, and innertubes made from novel C4to C7isoolefin based polymers with new sequence distributions or that are substantially free of long chain branching.
