The present invention relates to a modified styrene-butadiene copolymer, a method for manufacturing the same, and a rubber composition comprising the same. More particularly, the present invention relates to: a novel styrene-butadiene copolymer in which a terminal is modified with a hydrophilic compound to increase dispersibility of silica; the method for manufacturing the same; and the rubber composition comprising the same. A copolymer according to the present invention is excellent in workability due to increased dispersibility of silica by hydrophilic end groups. In addition, processed products (for example, tires) manufactured using the same have excellent tensile strength, wear resistance, and wet road resistance.
본 발명은 변성 스티렌-부타디엔 공중합체, 이의 제조방법 및 이를 포함하는 고무 조성물에 관한 것으로, 보다 상세하게는 말단이 친수성 화합물로 변성되어 실리카의 분산성이 증대된 신규 스티렌-부타디엔 공중합체, 이의 제조방법 및 이를 포함하는 고무 조성물에 관한 것이다. 본 발명에 따른 공중합체는 친수성 말단기로 인해 실리카의 분산성이 증대되어 가공성이 우수하고 이를 이용하여 제조된 가공품(예컨대, 타이어)은 인장강도, 내마모성 및 젖은 노면 저항성이 우수하다.
