Abstract

The invention relates to a processes for preparing nanocomposites comprising rubber ionomers which were prepared by an energy efficient, environmentally favorable process that uses a common medium for solution polymerization, bromination of rubber and optionally subsequent polymer nanocomposite formation. Polymer nanocomposites according to the present invention exhibit high oxygen impermeability.
