| Abstract: |
| The damping coefficient（tanδ） and dynamic stiffness of BR/SBR vulcanizates at different temperature and frequency were studied.The results showed that，neither tanδ nor dynamic stiffness exhibited strong dependence on the frequency from 80 Hz to 130 Hz.At a given frequency，as the temperature raised，tanδ increased,and the dynamic stiffness reduced firstly and then increased. |
