Abstract RU 2709516 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a terminal modified diene. Described is a method of producing modified diene rubber obtained by solution polymerisation. Conjugated diene compound and the aromatic vinyl compound in the hydrocarbon are initiated by means of an organolithium compound. Upon completion of polymerisation, a tin compound is added to treat diene rubber such that the content of the three- or more branched components is 5–30 %. Silane compound is then added, wherein content of two- or more branched component with silane compound of diene rubber is 30 % or less. Then obtained alkoxysilane-modified diene rubber is coagulated by steam and dried. Described also is a rubber composition.

EFFECT: modified diene rubber has excellent elasticity with good storage stability and high reactivity with silicon dioxide.
