| Abstract: |
| The interaction between carbon black， silica/coupling agent or carbon black/coupling agent/silica and NR/BR and its influence on the properties of vulcanizate were investigated by NH3 absorpt ionmethod .The results showed that the covalent bonds accounted for 40%in the rubber-black bonds，while the physical bonds were predominant；the covalent bonds accounted for 66% in rubber-coupling agent-silica bonds；and the covalent bonds accounted for 71%～73%in rubber-coupling agent-silica-black bonds. |
