The present invention relates to a modified conjugated diene-based polymer having excellent affinity with a filler, a method for preparing the same, a rubber composition comprising the same, and a tire obtained by using the rubber composition. The modified conjugated diene-based polymer according to the present invention has a tin compound-derived group bound to one end thereof and an aminosilane compound-derived group bound to the other end thereof, and thus can show excellent affinity not only with a silica-based filler but also with a carbon black-based filler. Therefore, the rubber composition comprising the modified conjugated diene-based polymer has excellent processability. As a result, a processed product (e.g. tire) obtained by using the rubber composition has excellent tensile strength, wear resistance and viscoelastic properties.
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.
