Heterografted amphiphilic cyclic homopolymers were prepared by the self-folding cyclization technique. The reversible addition–fragmentation chain transfer (RAFT) polymerization of N,N′-disubstituted acrylamide with oligo(ethylene glycol) (OEG) and octyl groups (OEGOAM) was performed to afford linear POEGOAM two terminal anthryl groups. After in water, single-chain polymeric nanoparticles (SCPNs) produced from precursors via hydrophobic interaction. By irradiating aqueous solution SCPNs 365 nm UV light, heterografted polymers synthesized intramolecular coupling Due presence alkyl hydrophilic OEG side chains, both can be employed as emulsifiers stabilize oil-in-water emulsions. Compared emulsion stabilized POEGOAM, that using emulsifier exhibited higher long-term high-temperature stabilities. result could attributed more compact conformation compared polymers, which provide stability newly created oil–water interface. This work not only enriches monomer scope technique but also expands application fields well providing a novel insight for design efficient emulsifiers.
