| 中文摘要: |
| 采用熔融法制备反式聚异戊二烯（TPI）接枝马来酸酐（MAH）（TPI-g-MAH），并与聚异戊二烯（IR）并用，研究IR/TPI-g-MAH并用胶的微观形态和物理性能。结果表明：以过氧化二异丙苯为引发剂的接枝产物TPI-g-MAH的差示扫描量热（DSC）曲线由未接枝TPI的DSC曲线的双峰分布转为单峰分布；与IR/TPI胶料相比，IR/TPI-g-MAH胶料的正硫化时间缩短，硫化胶的界面相容性和白炭黑分散性改善，物理性能和耐磨性能提高。 |
| 英文摘要: |
| 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. |
