摘　　要：研究了反式异戊橡胶合金(TPIR)的结晶性能、加工性能和力学性能及在轿车胎面胶溶聚丁苯橡胶/顺丁橡胶(SSBR/BR)中的应用.研究结果表明,与无定形SSBR和BR相比,TPIR生胶具有常温可结晶性,因此TPIR具有较高的格林强度.毛细管挤出行为研究结果表明,TPIR具有优异的挤出性能,挤出物外观光滑,挤出涨大比小.与SSBR/BR混炼胶相比,用TPIR改性后的SSBR/BR/TPIR混炼胶的格林强度与100%定伸应力随TPIR含量的增加而提高.经150℃硫化反应后制备的SSBR/BR/TPIR硫化胶物理机械性能优异:不仅耐湿滑性能、耐磨耗性能及压缩强度较对比胶提高,其伸张疲劳性能较对比胶提高4倍以上.透射电子显微镜(TEM)及填料分散仪表征结果表明,与SSBR/BR硫化胶相比,SSBR/BR/TPIR硫化胶的填料聚集体平均尺寸降低2μm,填料分散性显著改善.表明TPIR是一种应用于高性能轿车胎面胶的理想胶料.The crystalline characteristics,processing and mechanical properties of trans-1,4-polyisoprene alloy rubber（TPIR） were studied. Then TPIR incorporated with solution polymerized butadiene-styrene rubber（SSBR）/cis-1,4-polybutadiene rubber（BR） blends were further investigated as passenger car radical（PCR）tire tread stocks. Compared with amorphous SSBR and BR,TPIR raw rubber showed improved green strength due to its crystallizability at room temperature. The capillary extrusion behavior of TPIR indicated that TPIR presented good extrusion behavior with smooth extrusion appearance and low extrusion swelling ratio. SSBR/BR/TPIR compounds showed increased green strength and 100% modulus with the increase in TPIR,when compared with SSBR/BR blends. After vulcanization,SSBR/BR/TPIR vulcanizes showed excellent physical and mechanical properties,such as increased wet skid resistance,wear resistance,compressive strength,and outstanding tensile fatigue resistance（increased by more than 4 times）. Carbon blacks and silica were proved to be dispersed much more uniformly in SSBR/BR/TPIR vulcanizates with much smaller aggregates than in SSBR/BR vulcanizates. So comprehensive speaking,TPIR as a novel synthetic rubber has the potentional application in PCR tire tread stock with superor performance.
