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.
