| Abstract: |
| Trans-polyisoprene（TPI） grafted maleic anhydride（MAH）（TPI-g-MAH） was prepared by melting method and then TPI-g-MAH was blended with isopreneisoprene（IR），the morphology and physical properties of IR/TPI-g-MAH blend were studied.The results showed that，differential scanning calorimetry（DSC） curves of grafted products TPI-g-MAH using DCP as initiator presented bimodal distribution，and that of ungrafted TPI presented bimodal distribution.Compared with IR/TPI compound，the optimum cure time of IR/TPI-g-MAH compound was reduced，the interfacial compatibility，the dispersion of silica，the physical properties and wear resistance of the vulcanizate were improved. |
