FIELD: chemistry.
SUBSTANCE: invention relates to grafted polymer containing: (a) a main copolymer chain containing links formed from isoolefin containing from 4 to 7 carbon atoms and alkyl styrene; and (b) one or more branches containing polycyclic aromatic hydrocarbon, where one or more branches are connected directly to an aromatic fragment contained in the main copolymer chain intended for the use as a dispersing agent for a nanofiller, and a method for its production. The invention also relates to a composition of elastomeric nanocomposite containing a matrix of halogen butyl rubber, graphite or graphene nanoparticles and the specified grafted polymer.
EFFECT: such compositions of elastomeric nanocomposite are suitable for use as sealing layers or chambers for tires.
