【摘要】 介绍反式-1,4-丁二烯-异戊二烯共聚橡胶（简称反式丁戊橡胶，TBIR）的特性及其在动态橡胶制品中的应用研究进展。TBIR由丁二烯和异戊二烯两种结构单元组成，具有高反式-1,4-结构，分子链柔顺，玻璃化温度低，可以改善天然橡胶、顺丁橡胶、丁苯橡胶等通用橡胶并用胶的相容性和共硫化特性及其填料分散性。含TBIR的胶料耐疲劳性能和耐磨性能优异、滚动阻力和生热低。TBIR在高性能绿色轮胎、减震制品、输送带、传动带、橡胶履带及健身弹力带等领域具有广阔的应用前景。更多还原

【Abstract】 The research progress of characteristics of trans-1,4-poly(butadiene-co-isoprene)copolymer rubber(TBIR) and its application in dynamic rubber products was introduced. TBIR was composed of butadiene unit and isoprene unit with high content of trans-1,4-structure,and its molecular chain was flexible and glass transition temperature was low.TBIR could improve the compatibility,covulcanization characteristics and filler dispersion of the rubber blends containing natural rubber,cis-1,4-polybutadiene rubber,styrene butadiene rubber and other general-purpose rubbers.The compounds with TBIR presented excellent fatigue resistance and wear resistance,low rolling resistance and low heat builtup.TBIR had broad application prospects in the fields of high performance green tires,damping products,conveyor belts,transmission belts,rubber tracks and fitness elastic belts.更多还原
