The present invention relates to a modified conjugated diene-based polymer, and a rubber composition comprising same. Provided is a modified conjugated diene-based polymer satisfying the following conditions: i) a Mooney viscosity of 75-100 (exclusive of 100) as measured at 110°C under the conditions of ASTM D1646; ii) a Mooney stress relaxation rate of at most 0.4 as measured at 110°C; iii) a weight average molecular weight of at least 750,000 g/mol; and iv) a molecular weight distribution (PDI; MWD) of 1.0-2.0.

    La présente invention concerne un polymère à base de diène conjugué modifié, et une composition de caoutchouc la comprenant. L'invention concerne un polymère à base de diène conjugué modifié satisfaisant les conditions suivantes : i) une consistance Mooney de 75-100 (à l'exclusion de 100) telle que mesurée à 110 °C dans les conditions de la norme ASTM D1646 ; ii) un taux de relaxation des contraintes Mooney d'au plus 0,4 tel que mesuré à 110 °C ; iii) un poids moléculaire moyen en poids d'au moins 750 000 g/mol ; et iv) une distribution de poids moléculaire (PDI ; MWD) de 1,0 à 2,0.

    본 발명은 변성 공액디엔계 중합체 및 이를 포함하는 고무 조성물에 관한 것으로, i) ASTM D1646 조건 및 110℃에서 측정한 무니 점도: 75 이상 100 미만, ii) 110℃에서 측정되는 무니 응력 완화율: 0.4 이하, iii) 중량평균 분자량: 750,000 g/mol 이상, 그리고 iv) 분자량 분포(PDI; MWD): 1.0 이상 2.0 이하인 조건을 충족하는 변성 공액디엔계 중합체를 제공한다.
