FIELD: chemistry.
SUBSTANCE: claimed invention relates to elastomer compositions, which include elastomer and graphite nanoparticles, to internal envelope of tyre, produced from thereof, to method of obtaining thereof and to method of producing product from thereof. Technical result is achieved by means of elastomer composition, which includes from 0.1 to 10 wt.p. of graphite nanoparticles, from 1 to 99 wt % of at least one functionalised elastomer component. Said component includes statistical copolymer, which has at least one link, derived from isomonoolefin with C4 to C7, with elastomer component being functionalised with combination of halogen and triethylammonium group. In addition, composition contains from 10 to 2000 wt.p. of at least one filling agent, which is not graphite.
EFFECT: improved properties of air holding by products and technological characteristics of obtaining said products.
