摘　　要：研究了负载型钒系反式-1,4-聚异戊二烯(TPI)不同用量对TPI/中乙烯基聚丁二烯(MVBR)并用胶物理性能和动态性能的影响。结果表明,随着TPI含量的增加,并用胶的正硫化时间延长,撕裂强度、扯断伸长率以及回弹性能均得到提高。同时加入TPI还可改善并用胶的耐磨性、滚动阻力和生热表现。The mechanical and dynamic properties of trans-1,4-polyisorpene(TPI with supported vanadium catalyst)/medium vinyl polybutadiene rubber(MVBR)blends with different TPI contents were studied.The results indicated that with the increase of the content of TPI,and the increase of optimum cure time,tear strength,elongation and resilience of TPI/MVBR blends have been improved.The abrasion resistence,rolling resistence and heat performance of the blends were also affected by TPI.
