FIELD: chemistry.

SUBSTANCE: invention relates to an elastomeric nanocomposite based on C₄-C₇-isoolefin, having improved operational characteristics and linking characteristics. The nanocomposite contains a copolymer formed from at least one C₄-C₇-isoolefin monomer and a multi-olefin monomer, and nanofiller containing smectite clay with a surfactant. The surfactant has the structure (R¹R²R³R⁴)N⁺, wherein R¹ denotes a link formed from benzyl, which may or may not be substituted, wherein R² is selected from a group which includes C₁-C₂₆-alkyls, C₂-C₂₆-alkenes and C₃-C₂₆-aryls, and wherein R³ and R⁴ are identical or different and are independently selected from a group which includes C₉-C₂₆-alkyls, C₉-C₂₆-alkenes and C₉-C₂₆-aryls.

EFFECT: obtained nanocomposites have improved mechanical and barrier properties when used in articles, where impermeability is required, such as the inner lining of tyres, chambers, tyre vulcanising diaphragms, hoses, medical stoppers, impermeable sheets and similar articles.
