摘要
在二异丙苯基氯／ＢＣｌ３／ＣＨ２Ｃｌ２／异丁烯聚合体系中．用ＢＢｒ３代替ＢＣｌ３进行聚合。通过测定聚合物的卤素官能团，以检验ＩＮＩＦＥＲ修正机理的正确性。结果表明，聚合物中溴官能度／氯官能度约为３：１。证明对Ｊ．Ｐ．Ｋｅｎｎｅｄｙ教授的ＩＮＩＦＥＲ机理的修正是正确的。
By using BBr3 instead of BCl3 in dicumyl chloride/ BX3 / CH2Cl2/ IB system and under usual polymerization conditions, then by charaterizing the products obtained, it was found Br content is by far greater than C1, this suggested the termination reaction predominantly resulted not from INIFER agent but from collapsing or BBr3C1-.
