| Abstract: |
| The dynamic mechanical property of molybdenum-catalyzed high 1,2-polybutadiene rubber（1,2-PBR） was investigated，and compared with that of BR and SBR.The results obtained from frequency，temperature and strain scanning tests showed that，G′of 1,2 PBR vulcanizate was lower and the G′ changed little with frequency because of the stable structure of filler network in 1,2 PBR vulcanizate which helped to achieve stable performance in variable application environments；and tanδ of 1,2 PBR vulcanizate was lower,which contributed to lower rolling resistance,lower heat build-up,and better high-speed performance. |
