  摘要：

  一种新的合成方法用于合成一种新的二官能和一种已知的三官能引发剂，即1,3-二(2-甲氧基-2-丙基)-5-异丙基苯和1,3,5-三(2-甲氧基-2-丙基)苯，分别用于制备双端和三端聚异丁烯。合成过程分为三个步骤：1) 1,3,5-三异丙基苯的催化过氧化，2) 将过氧化物还原为相应的醇，3) 对醇进行甲基化。通过控制关键过氧化步骤的转化率，可以控制二官能和三官能中间体的相对比例。通过使用1,3-二(2-甲氧基-2-丙基)-5-异丙基苯，可以合成具有良好定义的二甲氧基双端聚异丁烯。尽管两种引发剂的总合成产率仅为14-20%，但由于起始材料的低成本、所使用的试剂和简单的操作，这些化合物代表迄今为止制备双端聚异丁烯最具成本效益的引发剂。
