FIELD: chemistry.
SUBSTANCE: invention relates to thermoplastic elastomer composition for sealing layer of pneumatic tyre. Thermoplastic elastomer composition contains (A) 100 wt pt of halogenated copoly(isoolefin-p-alkylstyrene) caoutchouc, (B) from 40 to 120 wt pt of polyamide resin and (C) from 0.5 to 10 wt pt of amine, containing, at least, one hydroxyl group. Amine (C) represents compound, described by formula (1): where R1 represents C1-30alkyl; R2 represents -(C2H4O)n-H, where n represents integer number in the range from 1 to 30; and R3 represents -(C2H4O)m-H, where m represents integer number in the range from 1 to 30, C1-30alkyl or hydrogen.
EFFECT: invention makes it possible to improve fatigue life.
