    摘要： A rubber composition for a tire tread includes an organosiloxane-modified diene polymer or a blend of the organosiloxane-modified diene polymer with another diene polymer and a silica or a mixture of the silica and carbon black, the organosiloxane-modified diene polymer being obtained by (a) polymerizing a diene monomer alone or a mixture of the diene monomer and aromatic vinyl monomer by the use of an alkali metal-containing polymerization initiator in a hydrocarbon solvent to give a diene polymer having an alkali metal-containing active end, and (b) reacting the alkali metal-containing active end of the diene polymer with an organosiloxane having at least one functional group selected from epoxy, alkoxyl, carbonyl, vinyl, chloro, bromo and iodo groups. The rubber composition for a tire tread is superior in processability and has both low rolling resistance and high wet-skid resistance by employing a decreased amount of a silane coupling agent.
