Title (EN) MODIFIED CONJUGATED DIENE-BASED POLYMER, METHOD FOR PREPARING SAME, AND RUBBER COMPOSITION CONTAINING SAME
(FR) POLYMÈRE DIÉNIQUE CONJUGUÉ MODIFIÉ, PROCÉDÉ DE PRÉPARATION ASSOCIÉ ET COMPOSITION DE CAOUTCHOUC LE CONTENANT

Abstract:
(EN) 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 containing the same, and a tire manufactured using the rubber composition. The modified conjugated diene-based polymer may have excellent affinity with a carbon black-based filler as well as a silica-based filler since a tin-based compound-derived group is linked to one terminal and an amino silane-based compound-derived group is linked to the other terminal in the modified conjugated diene-based polymer. Thus, the rubber composition containing the modified conjugated diene-based polymer can have excellent processability, and resultantly, the processed product (e.g., a tire) manufactured using the rubber composition may have excellent tensile strength, abrasion resistance, and viscoelastic characteristics.
(FR) La présente invention concerne un polymère diénique conjugué modifié présentant une excellente affinité avec une charge, un procédé de préparation associé, une composition de caoutchouc le contenant, et un pneu fabriqué à l'aide de la composition de caoutchouc. Le polymère diénique conjugué modifié peut avoir une excellente affinité avec une charge à base de noir de carbone ainsi qu'une charge à base de silice, étant donné qu'un groupe dérivé d'un composé à base d'étain est lié à une extrémité et qu'un groupe dérivé d'un composé à base d'aminosilane est lié à l'autre extrémité dans le polymère diénique conjugué modifié. Ainsi, la composition de caoutchouc contenant le polymère diénique conjugué modifié peut avoir une excellente aptitude au traitement, et par conséquent, le produit traité (par exemple, un pneu) fabriqué à l'aide de la composition de caoutchouc peut présenter une excellente résistance à la traction, une résistance à l'abrasion et des caractéristiques viscoélastiques.
(KO) 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.
