Controlled radical polymerization (CRP) has both revolutionized the synthesis of linear polymers and enabled unprecedented topological complexity. While the synthesis of many polymeric architectures requires careful planning and specialized precursors, branched macromolecules such as segmented hyperbranched polymers (SHPs), knotted polymers, core‐crosslinked stars (CCSs), and more can be synthesized through the copolymerization of vinyl monomers and divinyl crosslinkers in only a few steps. In the nearly two decades since its discovery, this strategy has helped elucidate the fundamental polymerization behavior of crosslinkers and also yielded a variety of functional and stimuli‐responsive materials. The purpose of this mini‐review is to therefore overview critical fundamental aspects of CRP of crosslinkers and materials derived therefrom. The process by which both SHPs and CCS polymers are synthesized, the effect of key reaction parameters and intriguing recent advances are described with the intent of both educating new researchers and inspiring new directions in this area. © 2020 Society of Industrial Chemistry

聚乙烯基交联剂的受控自由基共聚：功能支化大分子的稳健路线

受控自由基聚合（CRP）彻底改变了线性聚合物的合成方法，并实现了前所未有的拓扑复杂性。尽管许多聚合物结构的合成需要仔细计划和专门的前体，但支链大分子（如节段超支化聚合物（SHP），打结的聚合物，核交联星（CCS）等）可以通过乙烯基单体和二乙烯基交联剂的共聚合来合成仅需几个步骤。自发现以来的近二十年中，该策略有助于阐明交联剂的基本聚合行为，并产生了多种功能和刺激响应材料。因此，本小结的目的是概述交联剂及其衍生材料的CRP的关键基本方面。描述了SHP和CCS聚合物的合成过程，关键反应参数的影响以及令人感兴趣的最新进展，目的是教育这一领域的新研究人员并激发新的方向。©2020工业化学学会
