摘　　要：对比了偶氮二异丁腈(AIBN)、偶氮二异丁酸二甲酯(AIBME)和过氧化—2—乙基己酸叔戊酯(TAPH)3种自由基引发剂的性质及优缺点。详细介绍了新型引发剂AIBME和TAPH的制备工艺及其在合成聚合物多元醇(POP)中的应用。AIBME和TAPH的综合性能均优于AIBN,代表了POP合成用自由基引发剂的发展方向。The properties, advantages and disadvantages of three kinds of free radical initiators including azodiisobutyronitrile(AIBN), dimethyl azobisisobutyrate(AIBME) and t-amyl peroxy-2-ethylhexanoate(TAPH) are compared. The preparation process of the novel initiators AIBME and TAPH and their applications in synthesis of polymer polyol(POP) are introduced in detail. The comprehensive performance of AIBME and TAPH is all superior to that of AIBN, they represent the development directions of free radical initiator for synthesis of POP.
