An AB-alternating copolymer is distinctly unique in comparison with other copolymers (e.g., random, gradient, and block) because the structure is uniform in terms of sequence: there is no composition distribution among the chains, and there are no consecutive sequence such as AA or AAA in one chain. Various types of alternating copolymers have been synthesized via strategic monomer design and advanced control of the copolymerization process. They exhibit the unique self-assembly behaviors and properties derived from the sequence, which are different from random or block copolymers in some cases. In this review, four topics related to alternating copolymers synthesized via chain-growth polymerization are reviewed: (1) how to control the alternating sequence; (2) sequence characterization; (3) self-assembly; and (4) functions.
与其他共聚物（如无规共聚物、梯度共聚物和嵌段共聚物）相比，AB交替共聚物具有明显独特之处，因为其结构在序列方面是均匀的：链之间不存在组成分布，且一条链中不存在诸如AA或AAA之类的连续序列。通过策略性的单体设计和对共聚过程的先进控制，已合成了各种类型的交替共聚物。它们展现出源自序列的独特自组装行为和性质，在某些情况下与无规或嵌段共聚物不同。在本综述中，对与通过链增长聚合合成的交替共聚物相关的四个主题进行了综述：（1）如何控制交替序列；（2）序列表征；（3）自组装；以及（4）功能。
