Abstract: Well-defined polyacrylonitrile (PAN) copolymers containing pendant 2-ureido-4[1H]-pyrimidone (UPy) units have been synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization. Copolymer compositions determined by 1H NMR spectroscopy were in good agreement with the monomer feed. The… read more here.
