There has been a growing interest in discovering new approaches for the preparation of step-growth polymers as they hold a large margin of polymer manufacture since the beginning of the synthetic polymer era. After their distinctive advantages have been realized, light induced processes have been adapted to almost all kinds of polymerization processes including step-growth polymerizations. This mini review focuses mainly on the new developments in the field of step-growth polymerizations activated by light induced processes. The new discoveries are generally based on light induced pericyclic reactions, ketene chemistry and radical coupling processes. In comparison to the conventional strategies, the advantages of these particular approaches are also discussed.

自从合成聚合物时代开始以来，发现逐步制备聚合物的新方法就引起了人们的兴趣，因为它们在聚合物生产中占有很大的比重。在认识到它们的独特优势之后，光诱导方法已经适应了几乎所有类型的聚合过程，包括逐步增长聚合。这篇小型综述主要关注光诱导过程激活的逐步聚合反应领域的新发展。新发现通常基于光诱导的周环反应，乙烯酮化学反应和自由基偶联过程。与常规策略相比，还讨论了这些特定方法的优点。
