Abstract
The invention is concerned with the field of polymer chemistry and relates to elastomeric materials as usable, for example, as an inner liner material for motor vehicle tires, and to the use thereof. The problem addressed by the present invention consists in specifying elastomeric materials having relatively low gas permeability. The problem is solved by elastomeric materials comprising butyl and/or halobutyl rubbers or mixtures thereof, with 1 to 20 phr of at least one liquid imidazolium salt and with 1 to 40 phr of at least one filler having a graphitic structure. The problem is additionally solved by the use of the inventive elastomeric materials for elastomer materials having low to very low gas permeability.
