Abstract
A process for producing a nanocomposite of a halogenated elastomer and an inorganic, exfoliated clay includes the in-situ protonation of a modifier, which may be an alkylamine, arylamine or an alkylarylamine. This process can be integrated with a polymer halogenation process. The nanocomposite so formed has improved air barrier properties and is suitable for use as a tire innerliner or innertube.
