An over-retardation epiphenomenon has been observed during RAFT polymerization of N-acryloylmorpholine mediated by several bio-functional dithioesters. This epiphenomenon has been related to termination reactions onto intermediate radicals. The resulting three-arm species have been observed for the first time in RAFT polymerization conditions by MALDI-TOF mass spectrometry.
