FIELD: chemistry.
SUBSTANCE: invention relates to silane-sulphide modified compounds used to obtain tyres and their components, belts, hoses, vibration dampers, and footwear components, and methods to produce them. A silane-sulfide modified polymer compound is suggested, which is obtained by reacting a living anionic elastomeric polymer being a polymer or copolymer of monomers selected from butadiene, styrene, isoprene and α-methylstyrene, and silane-sulphide modifier of specific structure. A silane-sulphide modified macromolecular compound may be offered in the form of polymer composition, and polymer composition can be vulcanized (cross-linked) by reacting with at least one curing agent to obtain a vulcanized polymer composition.
EFFECT: invention allows producing tyres with low hysteresis loss and a rational relation of rolling resistance to wet road surface adhesion.
