본 발명은 충진제와의 친화성이 우수한 변성 공액디엔계 중합체, 이의 제조방법, 이를 포함하는 고무 조성물 및 상기 고무 조성물을 이용하여 제조된 타이어에 관한 것이다. 이에 따른 변성 공액디엔계 중합체는 일 말단에 주석계 화합물 유래기가 결합되어 있고, 나머지 일 말단에 아미노 실란계 화합물 유래기가 결합되어 있어 실리카계 충진제뿐 아니라 카본블랙계 충진제와의 친화성이 우수할 수 있다. 이에, 상기 변성 공액디엔계 중합체를 포함하는 고무 조성물의 가공성이 우수할 수 있으며, 결과적으로 상기 고무 조성물을 이용하여 제조된 가공품(예컨대, 타이어)는 인장강도, 내마모성 및 점탄성 특성이 우수할 수 있다.

    The present disclosure relates to a modified conjugated diene-based polymer having excellent affinity with a filler, a method for preparing the same, a rubber composition including the same and a tire manufactured using the rubber composition. The modified conjugated diene-based polymer according thereto has a tin-based compound-derived group bind on one end, and a silane-based compound-derived group bind on the other end, and therefore, may have excellent affinity with a carbon black-based filler as well as a silica-based filler. Accordingly, a rubber composition including the modified conjugated diene-based polymer may have excellent processability, and as a result, processed goods (for example, tires) manufactured using the rubber composition may have excellent tensile strength, wear resistance and viscoelastic property.
