FIELD: chemistry.

SUBSTANCE: invention relates to rubber mixtures and can be used in moulded articles. The rubber mixture contains (A) at least one butadiene-styrene rubber, (B) at least one filler and (C) at least one (poly)sulphide organo(alkylpolyether silane) of general formula [(x) (x') (x")Si-R^I]₂-S_m (I). The rubber mixture is obtained by mixing at least one butadiene-styrene rubber, at least one filler and at least one (poly)sulphide organo(alkylpolyether silane) of formula I.

EFFECT: invention enables to lower release of alcohol when mixing a rubber mixture and increase the elongation ratio at break of rubber while preserving rapture resistance properties.
