This perspective article is prepared in the memory of Anthony Ledwith who discovered Free Radical Promoted Cationic Polymerization (FRPCP) as a versatile photoinitiating system for cationic polymerization about four decades ago. Mechanistically, distinct modes for the photochemical formation of electron donor radicals in the UV, Vis and NIR range that can be oxidized to reactive cations to initiate the cationic polymerization of oxiranes and vinyl monomers are discussed. The dual polymerization strategies that have been applied to combine FRPCP with the other modes of polymerization processes are presented.

发现自由基40年后，光诱导的自由基促进了阳离子聚合

本文是为纪念安东尼·莱德威斯（Anthony Ledwith）而编写的，安东尼·莱德威斯（Anthony Ledwith）大约四十年前发现了自由基促进的阳离子聚合（FRPCP）作为一种多功能的阳离子聚合光引发体系。从机理上讲，讨论了可在紫外线，可见光和近红外范围内光化学形成电子供体基团的不同模式，该模式可被氧化成反应性阳离子以引发环氧乙烷和乙烯基单体的阳离子聚合。提出了将FRPCP与其他聚合过程模式结合使用的双重聚合策略。
