Fig. 5: Interconvertible radical and cationic RAFT polymerization via switching thiocarbonylthio end-groups.

a Synthesis of PiBVE-b-PMA and PiBVE-b-PS block copolymers through the transition from cationic to radical RAFT polymerization by DTC-to-TTC switching. CVM conjugated vinyl monomer. b MALDI-TOF MS spectra and c GPC trances for PiBVE precursor, intermediate, and block copolymers. d Synthesis of PMA-b-PiBVE and PMA-b-PMOS through the transition from radical to cationic RAFT polymerization by TTC-to-DTC switching. e MALDI-TOF MS spectra and f GPC trances for PMA precursor, intermediate, and block copolymers.
