FIELD: technological processes.
SUBSTANCE: invention relates to methods of producing rubber through solution polymerization. Disclosed is a method of producing rubber, which includes (co)polymerization of at least one diene monomer, and optionally at least one vinyl aromatic monomer, and a vinylsilicon compound in the presence of a functionalizing lithium initiator, and modification of the obtained (co)polymer with a polyfunctional silicon-containing agent. Functionalizing lithium initiator is obtained by reacting an organolithium compound, a secondary amine and a diene-containing compound. Also disclosed are rubber obtained using said method, rubber compositions and rubber based thereon, semi-finished products and tires including similar rubber.
EFFECT: disclosed method enables to obtain rubber compositions and rubber based thereon, characterized by an improved complex of hysteresis properties.
