| 中文摘要: |
| 研究了反式-1，4-聚异戊二烯（TPI）硫化胶及其与BR，SBR，NR共混硫化胶的性能。结果表明，通过控制硫黄用量即交联密度，可使TPI硫化胶具有优异的力学和动态力学性能；TPI与BR，SBR，NR共混，工艺性能良好，当TPI/BR，TPI/SBR和TPI/NR共混比小于50/50时，共混硫化胶的力学和动态力学性能优于BR，SBR和NR硫化胶，特别是拉伸疲劳寿命大大延长，这正是高性能轮胎所需要的。 |
| 英文摘要: |
| The properties of vulcanizates of trans-1，4-polyisoprene（TPI）and its blends with BR，SBR or NR were studied. The results showed that the excellent mechanical and dynamical properties were obtained by controlling the sulfur level，that is crosslink density；the blends of TPI with BR，SBR or NR featured good processibility；the mechanical and dynamic properties of TPI/BR，TPI/SBR or TPI/N R vulcanizates were better than those of BR，SBR or NR vulcanizates when the blending ratio was lower than 50/50，in particular the tension fatigue property，which was just the property needed by performance tire，improved signifcantly. |
