Abstract:
(EN) The present invention relates to a rubber composition which has excellent tensile properties and viscoelastic properties and comprises a modified conjugated diene-based polymer. Accordingly, the rubber composition can select and include a modified conjugated diene-based polymer in accordance with desired tensile properties and viscoelastic properties by predicting in advance the correlation between the modification rate of the modified conjugated diene-based polymer and the dynamic viscoelasticity loss factor of the rubber composition at 60℃ by way of mathematical equation 1 and mathematical equation 2, and thus the rubber composition may exhibit excellent mixing properties.
(FR) La présente invention concerne une composition de caoutchouc qui présente d'excellentes propriétés à la traction et propriétés viscoélastiques et qui comprend un polymère à base de diène conjugué modifié. Par conséquent, la composition de caoutchouc permet de sélectionner et de comprendre un polymère à base de diène conjugué modifié en fonction de propriétés à la traction et de propriétés viscoélastiques souhaitées par la prédiction à l'avance de la corrélation entre le taux de modification du polymère à base de diène conjugué modifié et le facteur de perte de viscoélasticité dynamique de la composition de caoutchouc à 60°C au moyen de l'équation mathématique 1 et de l'équation mathématique 2, et ainsi la composition de caoutchouc peut présenter d'excellentes propriétés de mélange.
(KO) 본 발명은 인장특성 및 점탄성 특성이 우수한, 변성 공액디엔계 중합체를 포함하는 고무 조성물에 관한 것이다. 이에 따른 고무 조성물은 변성 공액디엔계 중합체의 변성률과 고무 조성물의 60℃에서의 동적 점탄성 손실계수와의 상관관계를 수학식 1 및 수학식 2를 통해 미리 예측함으로써 목적하는 인장특성 및 점탄성 특성에 맞게 변성 공액디엔계 중합체를 선택하여 포함할 수 있으며, 이에 우수한 배합 특성을 나타낼 수 있다.
