Patent number: 11505624Abstract: The present invention relates to a rubber composition having excellent tensile properties and viscoelasticity properties and including a modified conjugated diene-based polymer. The rubber composition may include a modified conjugated diene-based polymer which is selected considering target tensile properties and viscoelasticity properties, by predicting in advance the correlation of the modification ratio of the modified conjugated diene-based polymer and the dynamic viscoelasticity loss coefficient at 60° C. of the rubber composition through Mathematical Formula 1 and Mathematical Formula 2. Therefore, excellent compounding properties may be shown.Type: GrantFiled: September 20, 2018Date of Patent: November 22, 2022Inventors: Jin Sook Ryu, Kyoung Hwan Oh, Woo Jin Cho, Suk Youn Kang, Sung Joon Oh, Sun Ok Oh
