摘　　要： 自由基聚合是生产高分子量聚合物的重要方法 ,“活性”/可控自由基聚合综合了自由基聚合和离子聚合的优点 ,使自由基聚合具有可控性。本文对目前可以实现“活性”/可控自由基聚合的途径和各自机理进行介绍 ,指出应该重视对“活性” Radical Polymerization is an important way to prepare high molecular weight polymers. But this way has some shortcomings, such as poor structure of its products. Ionic polymerization has the characteristic of keeping control the structure of polymer. ‘Living’/controlled radical polymerization integrates the merits of radical polymerization and ionic polymerization to make its reactive process controlled and produce polymers with ideal structure. In the paper, five methods to realize‘Living’/controlled radical polymerization and each peculiarities were introduced. It must emphasized that the research on ‘Living’/controlled radical polymerization and apply this technology appropriately to produce the needed polymers should be attached importance.
