“…Our findings showed that high photocatalyst (PC) concentrations and blue LED wavelengths were optimal for this reaction system. 172 With the advancements in reactive cationic and lightcontrolled polymerization, cationic RAFT polymerization has gained considerable attention in conventional systems, drawing inspiration from photoinitiated cationic RAFT polymerization. [173][174][175][176][177][178] The control degree during polymerization has significantly improved, especially in photoinitiated polymerization where chain growth is directly regulated by light.…”

Traditional living/controlled cationic polymerization provides a simple synthetic route for the preparation of various polymers with set molecular weight, narrow molecular weight distribution, and clear structure. Nowadays, under the requirements of sustainable development, it is very important to explore the green chemical technology in depth. This review offers an overview of initiation systems, reaction media, polymerization techniques, and monomers, with the aim of summarizing environmentally friendly methods utilized in the field of cationic polymerization over the past 15 years. It covers a variety of directions from traditional initiation systems to green initiators, from corrosive solvents to environmentally friendly solvents, from drop initiation to external stimulation initiation, from petroleum fractionated monomers to bio‐based monomers. These methods and Techniques aim to develop advanced high‐quality polymer products using cationic polymerization, and achieving efficient energy savings and reducing emissions. The ongoing exploration of green‐controlled cationic polymerization holds promise for opening up new avenues and novel technology for high‐performance polyolefin materials.

Temporal control of chain growth is a central challenge for photoinitiated active polymerization. In this work, we introduced an iridium salt complex‐based catalyst system to achieve fine temporal control of the chain growth process. By electrochemical analysis, compared with the pyran salt photocatalyst, it was found that the iridium salt complex could promote the chain transfer of active species to reversible addition‐fragmentation chain transfer polymerization (RAFT) reagent, thereby generating dormant species, which provided the possibility of time control of the polymerization process. Using this catalytic system, we successfully achieved homopolymerization of vinyl ethers with different substituents and random copolymerization with isobutyl vinyl ethers, which is not only pointed the way for broadening the monomer selection in the future, but also provided an innovative way to prepare new functionalized materials.

Cationic polymerization is an important branch of polymer chemistry. Traditional cationic polymerization must be carried out in anhydrous and low temperature environment, with harsh operating conditions, high operating costs and high energy consumption. Visible light induced cationic polymerization is simple, environmentally friendly, and low‐cost, so it has become a research hotspot of living cationic polymerization. This paper gives an overview of the recent advances (mainly from 2015 to 2023) on visible‐light‐induced cationic polymerization, with a focus on visible‐light‐initiated and visible‐light‐controlled cationic polymerization. On the basis of controlling cationic polymerization to achieve macromolecular reaction engineering, the realization of temporal scale control will be the main development direction in the future.
