Published in 2022 at "Macromolecular rapid communications"

DOI: 10.1002/marc.202200096

Abstract: A new family of polyampholytes (PAMs) is described in which both the basic and acidic groups are based on nitrogen functional groups. RAFT-prepared poly(pentafluorophenyl acrylate) was quantitatively modified sequentially with 3-picolylamine and 5-aminotetrazole, yielding the… read more here.
