Herein, a series of ternary amphiphilic amide-containing bottlebrushes were synthesized by photoiniferter (PI-RAFT) polymerization of macromonomers in continuous-flow mode using trithiocarbonate as a chain transfer agent. Visible light-mediated polymerization of macromonomers under mild conditions enabled the preparation of thermoresponsive copolymers with low dispersity and high yields in a very short time, which is not typical for the classical reversible addition-fragmentation chain transfer process. Methoxy oligo(ethylene glycol) methacrylate and alkoxy(C-C) oligo(ethylene glycol) methacrylate were used as the basic monomers providing amphiphilic and thermoresponsive properties.

- The amphiphilic block copolymer was created by reacting chain transfer agents during the polymerization process of specific acrylamides, resulting in a copolymer with a conversion rate of 68% and a high molecular weight of 490,000 g/mol.
- The study focused on the colloidal chemical properties of Langmuir monolayers and Langmuir-Blodgett films formed from the synthesized block copolymer, comparing it with a functional polymer made of poly(-isopropylacrylamide).
- Results indicated that the monolayers of the block copolymer exhibited high collapse pressures regardless of subphase acidity, and their Langmuir-Blodgett films displayed a unique comb-like structure
