Abstract
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.
