An alternating copolymer is a type of copolymer with a strictly alternating arrangement of two different monomer units. For example, an alternating copolymer of monomers A and B would have a structure like: -A-B-A-B-A-B-. This regular structure can lead to unique properties compared to random or block copolymers.

交替共聚物是一种共聚物，其中两种不同的单体单元严格交替排列。例如，单体 A 和 B 的交替共聚物将具有如下结构：-A-B-A-B-A-B-。与无规共聚物或嵌段共聚物相比，这种规则的结构可以产生独特的性能。
