This is a specific type of anionic polymerization where the monomer is a cyclic compound. The polymerization proceeds by opening the ring of the monomer and adding it to the growing polymer chain. This method is commonly used to synthesize polymers like polyesters, polyamides, and polyethers.

这是一种特殊类型的阴离子聚合，其中单体是环状化合物。聚合反应通过打开单体的环并将其添加到不断增长的聚合物链中来进行。该方法常用于合成聚酯、聚酰胺和聚醚等聚合物。
