Provided is a rubber composition for tire tread comprising: 30-80 wt% of polybutadiene having 10-50 wt% of cis-1,4 bonds and the glass transition temperature from -100 °C to -50 °C; and 20-70 wt% of a copolymer including an aromatic vinyl monomer and a conjugated diene monomer. The rubber composition for tire tread has improved dynamic properties, mechanical properties and wear resistance.

    본 발명의 일 측면은, 시스-1,4 결합의 함량이 10~50중량%이고 유리전이온도가 -100~-50℃인 폴리부타디엔 30~80중량%; 및 방향족 비닐 단량체 및 공액 디엔 단량체로 이루어진 공중합체 20~70중량%;를 포함하는 타이어 트레드 고무 조성물을 제공한다.
