The present invention relates to a method of producing a rubber, comprising (co)polymerizing at least one diene monomer and optionally at least one vinylaromatic monomer, and a vinyl-silicone compound, in the presence of a functionalizing lithium initiator, and modifying the obtained (co)polymer by a poly functional silicon-containing agent. The functionalizing lithium initiator is obtained by reacting an organolithium compound, a secondary amine and a diene-containing compound. In addition, the instant inventon relates to rubbers obtained by said method, rubber compositions and vulcanizates based thereon, semi-finished products and tires, comprising such a rubber. The present invention provides obtaining of rubber compositions and vulcanizates based thereon characterized by the improved complex of histeresis properties.
