中文摘要:
      以负载型TiCl4/MgCl2-Al（i-Bu）3为催化体系合成高反式丁二烯（Bd）-异戊二烯（Ip）共聚橡胶（TBIR），考察催化体系陈化方式和条件对聚合转化率的影响。结果表明，催化体系陈化有利于提高聚合转化率；三元陈化催化体系的聚合转化率大于二元陈化催化体系。三元陈化催化体系的优化陈化条件为：Ip/Ti摩尔比 20；Al/Ti摩尔比 20；加料顺序 TiCl4/MgCl2，Al（i-Bu）3，Ip；温度 20 ℃；时间 5～10 min。
英文摘要:
      The effect of the aging mode and condition of the supported TiCl4/MgCl2-Al（i-Bu）3 catalyst system on the conversion ratio during the polymerization of high trans-butadiene(Bd)-isoprene(Ip) copolymer(TBIR) was investigated.The results showed that the aging of catalyst system was beneficial to increase the conversion ratio during polymerization；the conversion ratio of aged ternary catalyst system was greater than that of aged binary catalyst system；and the optimized aging condition of the aged ternary catalyst system was as follows:Ip/Ti mole ratio 20，Al/Ti mole ratio 20，addition order TiCl4→MgCl2→Al（i-Bu）3→Ip，temperature 20 ℃ and time 5～10 min.
