Abstract:考察了以乙基四氢糠基醚(ETE)、乙氧基吗啉(EOEM)或四氢糠醇钠(THFAONa)作为改性剂,在改性剂与正丁基锂引发剂的摩尔比为1/1的条件下,对负离子聚合法合成的乙烯基聚丁二烯聚合反应速率及乙烯基含量的影响.结果表明,该3种改性剂都能显著加快聚合反应速率,在50℃时,各调节体系的聚合反应速率由大到小依次为THFAONa,ETE,EOEM;增加聚丁二烯乙烯基含量的能力由大到小依次为THFAONa,ETE,EOEM.在70℃下,ETE,EOEM和THFAONa改性体系得到的产物的乙烯基质量分数分别为49.2%,47.5%,52.9%,高于二哌啶乙烷在同样条件下的乙烯基质量分数.
