Hyperbranched polymers (HBPs), a unique class of dendritic macromolecules, have received continuous interest from macromolecular scientists due to their inherent properties such as high level of functional terminal units, high solubility, and low viscosity. Despite enormous efforts devoted to the synthesis of HBPs by traditional methods such as single and double monomer strategies involving step-growth polymerization and self-condensing vinyl polymerization (SCVP) processes, there have been limited attempts to employ light-induced processes. Photochemical methods, however, exhibit distinct advantages not characteristically disclosed by traditional ones, such as spatial and temporal control, low energy, and site-specific activation. This review, after a brief summary of the conventional methods, presents the unique features and the key functionalities of the inimers for photoinduced SCVP and strategies for preparing HBPs.
超支化聚合物（HBPs）是一类独特的树枝状大分子，由于其具有高官能度端基、高溶解性和低粘度等固有特性，一直受到高分子科学家的关注。尽管人们已经投入了大量的精力通过传统方法（如涉及逐步聚合和自缩合乙烯基聚合（SCVP）过程的单和双单体策略）来合成 HBPs，但利用光诱导过程的尝试却有限。然而，光化学方法具有传统方法所不具有的明显优势，例如时空控制、低能量和特异性激活。在简要总结了传统方法之后，本综述介绍了亚稳态引发剂用于光诱导 SCVP 的独特特征和关键功能以及制备 HBPs 的策略。
