This paper reviews the precise synthesis of many-armed and multi-compositional star-branched polymers, exact graft (co)polymers, and structurally well-defined dendrimer-like star-branched polymers, which are synthetically difficult, by a commonly-featured iterative methodology combining living anionic polymerization with branched reactions to design branched polymers. The methodology basically involves only two synthetic steps; (a) preparation of a polymeric building block corresponding to each branched polymer and (b) connection of the resulting building unit to another unit. The synthetic steps were repeated in a stepwise fashion several times to successively synthesize a series of well-defined target branched polymers.
本文综述了通过将活性阴离子聚合与支化反应相结合的具有共同特征的迭代方法来精确合成多臂和多组分星形支化聚合物、精确接枝（共）聚合物以及结构明确的树枝状星形支化聚合物的方法，这些聚合物的合成具有一定难度。该方法基本上只涉及两个合成步骤：（a）制备与每种支化聚合物相对应的聚合物结构单元，以及（b）将所得的结构单元与另一个单元连接。这些合成步骤以逐步方式重复多次，以相继合成一系列结构明确的目标支化聚合物。
