Preparation of α,ω‐heterobifunctionalized poly(N‐vinylpyrrolidone) via a bis‐clickable RAFT reagent

Abstract: A novel trithiocarbonate reversible addition−fragmentation chain transfer (RAFT) reagent, 3‐azidopropyl (4‐[fluorosulfonyl]benzyl)trithiocarbonate (Az‐FSBCT), which has both clickable azidopropyl and sulfonyl fluoride moieties, was designed and synthesized. Using the RAFT agent Az‐FSBCT and triethylboron as an initiator, well‐defined poly(N‐vinylpyrrolidone) (PVP), in which the azide and sulfonyl fluoride groups are at the α and ω positions of the polymer chains, were prepared without prior deoxygenation at ro… Show more

“…However after the polymerization of PEG at the end of the PVP-Tempo, a broad peak was observed at 3391 cm -1 due to the presence of O–H groups in the PEG 26 . The broader peak further confirms the possibility of the formation of intramolecular hydrogen bonding 45 . The C–H stretching vibrations cause the modest peak that was measured at 2800 cm -1 .…”
