SILANE MIXTURES AND METHOD FOR PREPARATION OF SUCH SILANE MIXTURES Russian patent published in 2022 - IPC C08L83/14 C08K5/548 C07F7/18 

FIELD: chemistry.

SUBSTANCE: invention relates to silane mixtures. A silane mixture for rubber mixtures is proposed, containing silane of the formula I and silane of the formula II, where R¹ have the same or different values and are C₁-C₁₀alkoxygroups, R² is absent, R³ and R⁴ have the same or different values and are an unbranched saturated aliphatic bivalent hydrocarbon group with C₁-C₃₀, y is equal to 3, and z is 2, while the molar ratio between silane of the formula I and silane of the formula II is from 20:80 to 85:15. A method for the production of a silane mixture is also proposed.

EFFECT: proposed silane mixture, when used as part of rubber mixtures, provides reduction in their rolling resistance, increase in a reinforcement degree, and reduction in abrasion.
