FIELD: chemistry.
SUBSTANCE: method involves a step for bringing an elastomer solution containing links based on C4-C7 isoolefins in an organic solvent into contact with a halogen to obtain halogenated elastomeric binder, treating a first portion of the binder with a clay dispersion to obtain a concentrated mother solution of the polymer-clay nanocomposite, mixing the mother solution with a second portion of the binder to obtain a halogenated elastomer-clay dispersed nanocomposite mixture, and extraction of the nanocomposite.
EFFECT: obtained nanocomposite has improved air-permeability and can be used as inner coating or tyre tube.
