FIELD: chemistry.
SUBSTANCE: invention relates to modified polymer compositions, used for manufacturing vulcanised compositions and products from them. Claimed composition, containing modified polymer, includes at least one branched modified polymer macromolecule, which contains at least one of structures ib; and at least one linear modified polymer macromolecule, which contains at least one of structures iib; where at least one branched modified polymer macromolecule and at least one linear modified polymer macromolecule each, independently, includes at least one amino group, selected from group, consisting of formulae (1A-1F) 
and their combinations.
EFFECT: invention provides low hysteresis loss of cross-linked elastomeric compositions, tyre treads with low rolling resistance, good adhesion to wet, as well as icy road surface.
