The present invention relates to a liquid butadiene compound with both ends modified, a method for preparing same, and a use thereof. More specifically, the present invention provides a liquid butadiene rubber compound with both ends modified that is synthesized using a chain transfer agent having a triethoxysilyl functional group and a tetrasulfide functional group, and a 1,3-butadiene monomer, a rubber composition for a tire comprising same, a method for preparing same, and the like. According to the present invention, by introducing a silica-friendly functional group at both ends of the chain, hysteresis or the like caused by the chain ends of an existing liquid butadiene rubber is controlled, and thus, various performances affecting fuel efficiency characteristics can be improved.

    La présente invention se rapporte à un composé de butadiène liquide ayant les deux extrémités modifiées, à son procédé de préparation et à son utilisation. Plus précisément, la présente invention concerne un composé de caoutchouc butadiène liquide ayant les deux extrémités modifiées qui est synthétisé à l'aide d'un agent de transfert de chaîne ayant un groupe fonctionnel triéthoxysilyle et un groupe fonctionnel tétrasulfure, et d'un monomère 1,3-butadiène, une composition de caoutchouc pour pneu le comprenant, son procédé de préparation et similaire. Selon la présente invention, par introduction d'un groupe fonctionnel respectueux de la silice aux deux extrémités de la chaîne, l'hystérésis ou similaire provoquée par les extrémités de chaîne d'un caoutchouc butadiène liquide existant est contrôlée, et ainsi, diverses performances affectant les caractéristiques d'efficacité de carburant peuvent être améliorées.

    본 발명은 양말단 변성 액상 부타디엔 화합물, 이의 제조방법, 및 이의 용도에 관한 것으로, 보다 상세하게는 트리에톡시실릴 작용기 및 테트라 설파이드 작용기를 가지는 사슬이동제와 1,3-부타디엔 모노머를 이용하여 합성한 양말단 변성 액상 부타디엔 고무 화합물, 이를 포함하는 타이어용 고무 조성물, 및 이의 제조방법 등을 제공한다. 본 발명에 따라 실리카 친화형 관능기를 사슬 양말단에 도입함으로써, 기존의 액상 부타디엔 고무의 사슬 말단으로부터 기인한 이력현상(hysteresis) 등을 조절하여 연비 특성에 영향을 주는 여러 성능들을 개선할 수 있다.
