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.

“…Compared with diblock copolymers, triblock copolymers contain more segments, and various blocks have different physicochemical properties. Environmentally stimuli‐responsive triblock copolymers have broad industrial significance and potential applications in controlled drug and gene release 12–16 . Triblock copolymers have relatively less been studied at the air/water interface than diblock copolymers 17–20 .…”

Langmuir film balance technique was used to study the subphase pH and temperature effects on the aggregation behavior of a dual-responsive triblock terpolymer poly[n-butyl acrylate-block-N-isopropylacrylamide-block-2-(dimethylamino)ethyl acrylate] (PnBA-b-PNIPAM-b-PDMAEA) at the air/water interface.Atomic force microscopy was used to observe the morphologies of its Langmuir-Blodgett (LB) films. At the interface, the terpolymer tends to form isolated circular micelles composed of hydrophobic PnBA cores and hydrophilic PNIPAM-PDMAEA coronas. The limiting areas in the surface pressure-molecular area isotherms under acidic and alkaline conditions are larger than that under neutral conditions due to the larger interfacial stretching degrees of PNIPAM blocks, which results from the strong electrostatic repulsions of the fully protonated PDMAEA blocks underwater in the acidic case. In our minds, the hysteresis degrees of the compressionÀexpansion cycles under different subphase pH conditions should mainly depend on the initial stretching degrees of the hydrophilic blocks. Under acidic conditions, the isotherms shift toward small areas with the increase of temperature due to the increased solubility of PNIPAM blocks. However, under alkaline conditions, the isotherms significantly exhibit the lower critical solution temperature behavior of PNIPAM blocks, which is a good example to build up the relationship between the interfacial and solution properties of block copolymers.
