摘　　要：研究反式-1,4-丁二烯-异戊二烯共聚橡胶(TBIR)的结晶性能、加工性能以及NR/BR/TBIR并用胶在轿车轮胎胎侧胶中的应用。结果表明:相比反式-1,4-聚异戊二烯(TPI),TBIR的结晶性能微弱、玻璃化温度更低;相比天然橡胶(NR)和顺丁橡胶(BR),TBIR具有优异的加工性能;相比NR,BR和TPI,TBIR的耐老化性能优异;相比NR/BR和NR/BR/TPI并用胶,NR/BR/TBIR(并用比为45/35/20)并用胶的物理性能优异,生热降低,耐裂口扩展性能显著提高。TBIR作为一种新型合成橡胶材料可应用于高耐疲劳轿车轮胎。The crystalline and processing properties of trans-1,4-poly（butadiene-co-isoprene） rubber（TBIR）and the properties of NR/BR/TBIR blends as the sidewall compound for PCR tire were investigated. The results showed that TBIR had much weaker crystallizability and lower glass transition temperature compared with trans-1,4-polyisoprene（TPI）. Compared with NR and BR,TBIR showed excellent extrusion property and better aging resistance. Compared with NR/BR and NR/BR/TPI blend,NR/BR/TBIR blend with the blending ratio of 45/35/20 possessed better physical properties,for example,lower heat built-up and better crack-growth resistance. TBIR,as a novel synthetic rubber material,was expected to have wide applications in PCR tire with high fatigue resistance.
