Abstract

See full text

Polycyclic aromatic hydrocarbon (PAH) functionalized isobutylene copolymers, methods for making a PAH functionalized isobutylene copolymer comprising combining a halogenated copolymer with a PAH in a solvent under basic conditions at a temperature ranging from 30° C. to 150° C., the use of these PAH functionalized copolymers as a dispersant in elastomeric nanocomposite compositions comprising a halobutyl rubber matrix and nanoparticles of graphite or graphene, and a tire innerliner or innertube produced from these elastomeric nanocomposite compositions is disclosed.
