| Abstract: |
| A SIBR was prepared by usingn-butyl lithium，cyclohexane，tetrahydrofuran，and tin tetrachloride as initiator，solvent，structure modifier and coupling agent respectively，and its properties were investigated.The results showed that the physical properties of SIBR vulcanizate were influenced by the properties of monomers and the addition time of structure modifier，and the physical properties of SIBR vulcanizate improved by the addition of structure modifier at the early mixing stage；and SIBR possessed lower Tg，better low temperature resistance，excellent wet traction and similar rolling resistance when compared to SSBR/BR/NR blend. |
