Provided is an all-season tire tread rubber composition in which braking performance and wear performance are secured at the same time. A rubber composition for tire tread according to the present disclosure comprises: 100 parts by weight of raw rubber comprising solution polymerized styrene-butadiene rubber which has a styrene content of 20 to 30 wt % and a vinyl content within butadiene of 20 to 30 wt %, and is manufactured by a continuous method; 90 to 110 parts by weight of silica; and 20 to 40 parts by weight of modified liquid butadiene rubber.

Disclosed is an interfacial polymer for a network used as a coupling agent in mixing of rubber-silica. More particularly, the interfacial polymer for a rubber-silica network is a block copolymer containing a copolymer of conjugated diene and vinyl aromatic monomers, in which when used as a coupling agent in the mixing of synthetic rubber and silica (an inorganic material), the polymer enhances silica dispersibility within the rubber, and improves compatibility and processability, resulting in considerable improvement in the dynamic property as well as the mechanical property of the rubber, and when used in a tire, etc., it enhances automobile braking performance and reduces rolling resistance.
